Combinational Logic Analysis - Technical MCQs

Q1:

The expression  can be directly implemented using only ________.

A an XOR gate

B an XNOR gate

C an AOI circuit

D three 2-input NAND gates

ANS:C - an AOI circuit

AOI means AND-OR-INVERT CIRCUIT.This circuit is implemented in the CMOS logic family.AOI perform one or more AND operation follwed by an OR opearation and Inversion.
