Two important characteristics of CMOS devices are ____________(a) High noise immunity(b) Low static power consumption(c) High resistivity(d) Both high noise immunity and low static power consumptionI had been asked this question by my college professor while I was bunking the class.My query is from Characteristics of CMOS topic in section Logic Families of Digital Circuits

Answer»

Right choice is (d) Both high noise immunity and low static power consumption

Explanation: TWO important characteristics of CMOS devices are high noise immunity and low static power consumption. SINCE one transistor of the pair is always off and the SERIES combination draws significant power only momentarily during switching between on and off states. Also, the performance of CMOS is not ALTERED with the presence of noise and thus it has high noise immunity.
