Question

An important characteristic of a CMOS circuit is the ____________

(a) Noise immunity

(b) Duality

(c) Symmetricity

(d) Noise Margin

This question was addressed to me in final exam.

Asked question is from Characteristics of CMOS topic in section Logic Families of Digital Circuits

Answer 1

The correct choice is (b) Duality

The explanation is: An important characteristic of a CMOS circuit is the duality that exists between its PMOS transistors and NMOS transistors. Due to the presence of two different types of transistors, the device has a complementary function.
