BiCMOS ( eng. Bipolar complementary metal oxide semiconductor , BiKMOS ) - manufacturing technology of integrated circuits using bipolar and CMOS transistors on a single chip . The technology allows you to create unique products that incorporate digital and analog circuits, combining the advantages of various types of transistors. Recently, the technology has spread in power circuits, for example, in voltage regulators .
A special area is microcircuits in which the logic elements are made according to CMOS technology, and the output stages are based on bipolar elements. This avoids a significant drawback of CMOS element circuits - large through currents at the time of switching from zero to single state. Such currents lead to the appearance of powerful pulsed noise, which limits the use of these microcircuits in radio devices. The use of BiCMOS technology allows combining the advantages of both MOS and TTL technologies, while avoiding their disadvantages.
Examples: 74 BCT Series, 74 ABT - Logic Gates.
