CMOS logic dissipates _______ power than NMOS logic circuits.(a) More(b) Less(c) Equal(d) Very HighI got this question in an interview for internship.The doubt is from Characteristics of CMOS in portion Logic Families of Digital Circuits

Answer»

Correct choice is (b) LESS

Easiest explanation: CMOS logic dissipates less power than NMOS logic circuits because CMOS dissipates power only when SWITCHING (“DYNAMIC power”). THUS, CMOS has less power consumption and is more efficient.
