Question

When was BiCMOS technology introduced?

(a) 1990

(b) 1991

(c) 1992

(d) 1989

This question was posed to me in an international level competition.

My doubt is from BiCMOS Logic Circuits in portion Logic Families of Digital Circuits

Answer 1

Right choice is (a) 1990

To explain I would say: BiCMOS technology was introduced in 1990s. BiCMOS is an evolved semiconductor technology that integrates two formerly separate semiconductor technologies those of the BJT and CMOS. CMOS ensures low power dissipation, smaller noise margin and higher packaging density, while BJT offers high switching speed and improved noise performance.
