bipolar CMOS (BiCMOS)
BiCMOS technology(BipolarCMOS) is a combination of the two main semiconductor technologies, bipolar technology and CMOS technology.
Logics from both technologies, BiCMOS and CMOS technology, combine the advantages of these semiconductor technologies. For example, CMOS technology is characterized by low power consumption and high input impedance, while bipolar circuits have high switching frequencies and short switching times.
In BiCMOS circuits, the input circuits are implemented in CMOS, while the output stages are bipolar. As a result, this technology has a high driver capability.
BiCMOS can operate in both ECL logic and TTL logic and is ideal for mixed- signal devices. Some chip manufacturers are developing chips with BiCMOS processes that combine analog, digital and power functions on a single chip.
