Logic families If the logic gate is not being used periodically a simple way of reducing the leakage currents in the gate would be to set the clock to '0' mode and making a input vector for the n-tree for which a maximum number of transistors are in 'off' mode. But when the clock is logically '0' the output is either dynamically held by the capacity of the two drain regions of the clocked transistors or logically floating (not connected). The speed of this type of logic gate is reduced both by the series clocking transistors and the fact that logic evaluation of inputs is only done in the high clock phase. www2.imm.dtu.dk /~s973741/logicfamilies.html

Digital Electronics DTL takes diode logic gates and adds a transistor to the output, in order to provide logic inversion and to restore the signal to full logic levels. One of those discarded ideas was to move beyond binary logic to circuits based on multi-valued logic in which the information density and processing efficiency of a circuit could theoretically be increased substantially without any further expensive "improvements" to the underlying fabrication technology. Resistor-transistor logic gates use Transistors to combine multiple input signals, which also amplify and invert the resulting combined signal. www.epanorama.net /links/digital.html   (4766 words)

Transistor to gate full custom functional abstraction tool With a focus on full-custom design, TLL is today capable of abstraction a wide variety of design styles; including: standard CMOS, pseudo-NMOS, pass-transistor logic, dynamic logic using complex (multi-phased) pre-charge, footed and non-footed domino logic, logic cascades, dual-rail or Cascode Voltage Switch Logic (CVSL). The produced combinational logic is optimized and expressed using 'and', 'or' and 'xor' operators. Quasi-linear complexity avoids well-known Boolean explosion by using a set of algorithms that clusters the logic in manageable blocks by analyzing the behavior of the design prior to performing the Boolean manipulations. www.edaone.com /tll.htm   (247 words)

EE Times UK - Cone "mapping" aids functional abstraction The cone approach is suitable for CMOS and NMOS logic in numerous styles including domino logic, pass-transistor logic, transmission-gate logic, and pre-charged logic and has handled "flat" netlists of up to four million transistors, according to Lester. There is also a mapping between cone netlist and logical gate structures and the HDL expression of those logical structures. The idea is to partition the circuit into extracted logical gates such that the states of all the circuit nodes connected to at least one transistor gate are defined. www.eetuk.com /showArticle.jhtml?articleID=12802004   (3304 words)

Lecture 3 Notes: Called pseudo-NMOS since NMOS only logic families used a long time ago (this family uses one PMOS transistor). This is a smaller logic family than CMOS since it does not have to have the complimentary PMOS tree. If PMOS Drive strength is equal to NMOS drive strength, Vol will only be Vdd/2. www.engin.brown.edu /courses/En160/lecture_notes/Lec_3_notes.class.htm   (1388 words)

Development of Electronics Manufacturing Engineering Instructional Materials for ECE Sophomores and Juniors ECE 214 emphasizes digital electronic logic devices and device families such as TTL (transistor-transistor logic), ECL (emitter- coupled logic), NMOS Field-Effect Transistors, and CMOS devices, which are the typical building blocks of modern digital microelectronics circuitry. Standard ECE undergraduate curricula include a sophhomore-level digital electronics course and a junior-level course in semiconductor devices and materials, both corses emphasizing the electrical physics and circuit behavior of digital and analog solid-state devices and integrated circuits. Faculty teaching these sophomore and junior semiconductor electronics courses are normally not experts in electronics manufacturing, and for that reason we ill require considerable assistance from industry in the development of appropriate materials. www.ecs.umass.edu /easn/projects/proj8.html   (1388 words)

CMOS technology demonstration As in NMOS technology, there are certain logic functions that can be realized very efficiently by CMOS gates. The main advantage of CMOS over NMOS and bipolar technology is the much smaller power dissipation.

EE 307-01 Group 4 Project An examination of a NAND gate’s truth table shows that for a logic low output, both inputs must be logic high; holding one of the inputs at “0” cannot produce a “falling edge”. In a typical CMOS NAND gate, the rising and falling transitions are asymmetrical due to the body effect on the upper NMOS transistor. The output of the symmetrical NAND gate does not depend upon which input had which voltage as it does with the 2-branch NAND gate of figure 3. www.calpoly.edu /~iclausen   (1705 words)

Museum Two further features of the 8080 CPU are the exclusion of clock logic and bus interface logic from the CPU chip. Unlike the 8008 the 8080 was not manufactured in MOS but in NMOS technology. The size of the silicon die on which the 8080 is etched had been reduced from one manufacturer to another (230 by 210 mils, or 48,300 square mils to 131 by 169 mils, or 22,139 square mils). www.cpu-museum.com /8080_e.htm   (852 words)

CMOS: Complementary Metal-Oxide-Semiconductor - Digital Cameras Outlet As in NMOS logic, a collection of n-type MOSFETs is arranged in a pull-down network (PDN) between the output and the low-voltage power supply rail. However, unlike NMOS, CMOS also has a collection of p-type MOSFETs (complementary to the n-type) in a pull-up network (PUN) between the output and high-voltage rail, in place of a resistor. Still, antistatic handling precautions continue to be enforced to prevent excessive energies from building up. www.digital-cameras-outlet.com /article/CMOS   (604 words)

Logical effort - Wikipedia, the free encyclopedia The logical effort of an inverter is defined to be g = 1 by noting that the input capacitance of a minimum size inverter has an NMOS input capacitance of 1, while the PMOS input capacitance is two. The method of logical effort, a term coined by Ivan Sutherland and Robert Sproull in 1991, is a straight-forward technique used to estimate delay in a CMOS circuit. The logical effort of a two-input NAND gate is calculated to be g = 4/3. en.wikipedia.org /wiki/Logical_effort   (604 words)

LVDCSL: A High Fan-in, High Performance Low Voltage Differential Current Switch Logic Family (ResearchIndex) Abstract: In this paper we present a Low Voltage Differential Current Switch Logic (LVDCSL) gate which is capable of achieving high performance for large fan-in gates. It is topologically a Cascode Voltage Switch Logic Gate with a cross-coupled inverter based... High fan-in is enabled by allowing large stacked NMOS tree heights using a pre-discharged NMOS tree, at the same time the power penalty of an increased number of internal nodes in the gate is mitigated by restricting internal node voltage swings. citeseer.ist.psu.edu /50956.html   (604 words)
