	Common emitter - Wikipedia, the free encyclopedia
		A common emitter is a type of electronic amplifier stage based on a bipolar transistor in series with a load element such as a resistor.
		The term "common emitter" refers to the fact that the emitter node of the transistor (indicated by an arrow symbol) is connected to a "common" power rail, typically the 0 volt reference or ground node.
		Common emitter circuits are used to amplify weak voltage signals, such as the faint radio signals detected by an antenna.

	NDS, Inc
		Common practice is to place the pipe on the bedding and carefully tamp the fill under the haunches to the specified compaction.
		For French drains, it is ideal to backfill drain trench with a gradation of gravel and stone, the coarser material at the bottom near the pipe followed by gradually finer material as the trench is filled.
		The size of the drain is correlated to the size of the planting pit and the percolation rate of the soil.

	Operational amplifier - Wikipedia, the free encyclopedia
		This is called the "differential input voltage." In its most common use, the op-amp's output voltage is controlled by feeding a fraction of the output signal back to the inverting input.
		Common mode gain — A perfect operational amplifier amplifies only the voltage difference between its two inputs, completely rejecting all voltages that are common to both.
		Q1 and Q2 are input emitter followers and together with the common base pair Q3 and Q4 form the differential input stage.

	Drains
		Drain lines can be costly and annoying if not taken care of.
		The most common service call for drain cleaners are the kitchen sink drains.
		Using chemicals such as the liquid drain uncloggers in a bottle melts through older pipes where the walls of the pipe are already thin.

	Olympus Microscopy Resource Center: Digital Imaging in Optical Microscopy - Concepts in Digital Imaging - CCD Blooming
		The most common clocking approach involves alternate switching of clock-voltage phases to force excess charge into the barrier region nested between the CCD silicon substrate and oxide layer, where it is recombined with electron "holes" in the crystalline silicon lattice.
		Drains enable integration time to be controlled independently of charge readout, which allows them to serve as an electronic exposure or shutter mechanism to limit pixel saturation and provide a more reliable shuttering method than is currently possible with mechanical devices.
		In contrast, vertical overflow drains are positioned in the charge accumulation site and have an electrostatic potential barrier that is limited to allow excess charge to overflow directly into the silicon substrate.

	diyAudio Forums Archive - Common Source versus Common Drain output stages
		This rise in output impedance is primarily due to the fact that the common source configuration does not use 100 percent negative self-feedback in the output stage that a source or emitter follower configuration has.
		The great benefit of using a common source configuration in a amplifier that drives a loudspeaker is that you gain the ability to control the output impedance via a selected amount of negative feedback around the stage.
		With BJT common emitter darlington output configuration, some low value resistor is to be connected between the bases of the drivers and ground, in order to define the overall open loop gain of the amplifier, independently of the loudspeaker impedance variations.

	JFET Common Drain Amplifier (Site not responding. Last check: 2007-11-02)
		The common drain FET amplifier is similar to the common collector configuration of the bipolar transistor.
		A general common drain JFET amplifier, self-biased, is shown in figure 5.18.
		This configuration, which is sometimes known as a source follower, is characterized by a voltage gain of less than unity, and features a large current gain as a result of having a very large input impedance and a small output impedance.

	Common Drain Problems and other Clogged Drain nightmares
		Most people will say "I have this clog and I used every kind of drain cleaner from Draino to liquid plumber and I even cleaned out the trap and ran a snake down the drain and nothing, it is still clogged".
		If a drain line goes 50 feet and the clogged section of the pipe is between 20 and 30 feet down the line, A 25 foot snake will not clear the clog.
		When the drain gets clogged passed the lower fixture, the water from the upper fixture has no place to go so it backs up in the lower fixture.

	Common base - Wikipedia, the free encyclopedia
		For the philosophical concept, please see Common base (Unification Thought).
		In electronics, common base or grounded-base refers to a type of bipolar transistor circuit configuration in which a transistor is connected such that its base terminal is wired to the ground or "common" rail of the circuit (or can be considered so for AC signals).
		In this configuration, the input signal is applied to the emitter, being the output at the collector.

	Transformer Oil Leak Repairs - Drain Plug Leak Repair Procedure by TDS
		Drain plugs are found at numerous locations on a transformer.
		The most common locations are on the bottom of radiator banks and tap changer compartments.
		If additional tightening does not stop these common thread leaks (Figure 1), then the plug has to be removed and repaired which entails draining the oil from the radiator bank or compartment.

	Drain Cleaners - Thick is Good
		Attempts to remove the clog with a plunger and a drain cleaning snake were futile.

	Active-mode operation - Chapter 5: JUNCTION FIELD-EFFECT TRANSISTORS - Volume III - Semiconductors
		A pair of opposing constant-current diodes is included in the model to facilitate current in either direction between source and drain, a trait made possible by the unipolar nature of the channel.
		The mathematical ratio between drain current (output) and gate-to-source voltage (input) is called transconductance, and it is measured in units of Siemens.
		The relationship between gate-source (control) voltage and drain (controlled) current is nonlinear: as gate-source voltage is decreased, drain current increases exponentially.

	Septic Tank Systems Cleaning Maintenace and Common Problems
		Clogs, smells, leaks and pipe breakage are among the more common drain problems: septic problems include dangerous sewer gas, bad smells and problems with lines and tanks.
		The first thing you need to know before working on a clogged drain is that the drain cleaners you see advertised on TV or on the supermarket shelves are made of dangerous chemicals that will eat through rubber gloves, skin, certain kinds of pipe, wood and anything else they touch.
		For a more healthy and safe alternative, try a natural drain cleaner, such as Drainbo, that is made from natually occuring bacteria that will fix a clogged drain, but won't hurt your drain pipes or the environment.

	Lessons In Electric Circuits -- Volume III (Semiconductors) - Chapter 6
		Notice how the source and drain leads connect to either end of the N channel, and how the gate lead attaches to a metal plate separated from the channel by a thin insulating barrier.
		Junction field-effect transistors are normally-on devices: with zero applied gate-to-source voltage, they allow maximum drain current (actually, you can coax a JFET into greater drain currents by applying a very small forward-bias voltage between gate and source, but this should never be done in practice for risk of damaging its fragile PN junction).
		Not surprisingly, the drain current is now regulated at a lower value of 2.5 µA (down from 10 µA with zero input voltage).

	Lessons In Electric Circuits -- Volume III (Semiconductors) - Chapter 5
		In a junction field-effect transistor, or JFET, the controlled current passes from source to drain, or from drain to source as the case may be.
		However, if a voltage is applied between gate and source of such polarity that it reverse-biases the PN junction, the flow between source and drain connections becomes limited, or regulated, just as it was for bipolar transistors with a set amount of base current.
		Of course, if you know beforehand which terminals on the device are the gate, source, and drain, you may connect a jumper wire between gate and source to eliminate any stored charge and then proceed to test source-drain continuity with no problem.

		The common source configuration for a FET is similar to the common emitter bipolar transistor configuration, and is shown in figure 5.17.
		The common source amplifier can provide both a voltage and current gain.
		Since the input resistance looking into the gate is extremely large the current gain available from the FET amplifier can be quite large, but the voltage gain is generally inferior to that available from a bipolar device.
