Consider the circuit as shown below, assume that all inputs are 0 during the pre-charge phase and all the internal nodes are initially 0V. Suppose all the nMOS transistors have the same Vtn0 = 0.4V. Ignore the body effect and calculate the voltage drop on Vo, if: (a) Only A changes to 1 (VDD=2.5) during the evaluate phase. (b) Both A and B change to 1 (VDD=2.5V) during the evaluate phase. (c) Only A, and C change to 1 (VDD=2.0V) during the evaluate phase.
You'll get a detailed, step-by-step and expert verified solution.
