Question

Consider the CMOS logic circuit below. What logic function does this circuit implement? (circle one. no explanation necessary) Y = A + (BC) Y = A + (BC) Y = A(B + C) Y = A(B+ C) If this circuit is fabricated in 0.25 mu m CMOS technology node, and all the transistors have the same gate length of 0.25 mu m and Q_s uses the minimum gate width of 0.25 mu m. select gate widths for the other transistors based on the gate sizing rule to make the current drivability of pull down or pull up network in this circuit the same as that of NMOS or PMOS in a basic minimum size inverter in 0.25 mu m node. Assume mu n=2.4mu p for 0.25 mu m node.

Explanation / Answer

MULTIPLE QUESTIONS PLEASE SPLIT:

ANS 1)

It is clear from the nmos part that either of B or C can conduct. But current must flow throw through A to form a conduction path. Futher if A and B or A and C conduct then the output is HIGH.

Hence the function implemented is A.(B+C) hence the option D is correct
