- Abbreviation of bipolar complementary metal-oxide semiconductor. An IC which incorporates technologies from both bipolar junction transistors and complementary metal-oxide transistors. This provides greater functionality, as it exploits the advantages of each. For instance, it makes the most of the speed and linearity of bipolar junction transistors, while also benefiting from the lower power dissipation and higher packing densities of complementary metal-oxide transistors. Used, for example, in logic chips which require higher speeds than would ordinarily be suitable for traditional logic chips. Its own abbreviation is BiCMOS.
