  BiCMOS - Wikipedia, the free encyclopedia
As a simple example of a BiCMOS circuit, consider a two-stage amplifier which uses a MOS transistor in the first stage and a BJT in the second.
It should be clear that this provides the high input resistance of the MOS and the low output resistance of a BJT amplifier.
BiCMOS as a fabrication process is not nearly as mature as either BJT or CMOS fabrication.

 BICMOS driver circuit with complementary outputs - United States Patent 4,871,928
A BICMOS inverter circuit having a high input impedance, improved switching characteristics, low power requirements, high noise immunity, high drive capability, an increased output voltage swing, reduced body effect, high current drivability and improved power dissipation comprises a CMOS inverter for receiving an input signal and bipolar push-pull output transistors for supplying an output.
For BICMOS arrays having a large number of devices, it is desirable that each CMOS device be of small size.
A further object of the present invention is to provide a BICMOS inverter circuit which provides both an output signal and the compliment of that output signal.

As indicated in Figure 2, BiCMOS for digital logic applications was actively developed between the late 1970s and the early 1990s.
The idea behind the development of BiCMOS for digital logic applications was to combine the characteristics of high-speed bipolar and low-power CMOS on the same chip.
Nonetheless, lateral pnp transistors are often used in bipolar analog circuits to improve circuit characteristics [11].

 Mixed Signal Design - RF CMOS or SiGe BiCMOS?
From its humble beginning in the late 1980s when it was looked at as nothing more than a scientific excercise at a few research labs, namely at IBM in the United States and Temic in Europe, to today where it is on the road map of every major semiconductor company.
Thus, for the first 0.35 µm SiGe BiCMOS process developed at Atmel, the Ft of the HBT device exceeded 45 GHz as compared to the Ft of the 0.35 µm NMOS, which was barely more than 20 GHz.
The BiCMOS process is more complex and, therefore, offers a few layers more that could be tapped as the diodes for the ESD protection.
