BiCMOS From Wikipedia, the free encyclopedia In integrated circuit technologies, BiCMOS , also called BiMOS , refers to the integration of bipolar junction transistors and CMOS technology into a single integrated circuit device. This technology has commercial application in amplifier and discrete component logic design. More recently it has become the technology of choice for power electronics products [ citation needed ] such as voltage regulators . History Historically, fabricating both bipolar and metal–oxide–semiconductor (MOS) transistors in a single integrated circuit proved difficult and uneconomical. Therefore, until recently most integrated circuits have used one or the other, according to application requirements. This all- one-or-the-other choice necessarily entailed an engineering compromise in many cases, particularly for mixed-signal integrated circuits , compared to the ideal case where the type of each transistor could be freely and independently chosen according to the function and purpose of that particlular transistor in the circuit. Bipolar transistors offer high speed, high [ citation needed ] gain , and low output resistance , which are excellent properties for high-frequency analog amplifiers, whereas CMOS technology offers high input resistance and is excellent for

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
