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 = 0.45V. CA = 50fF, CB = 10fF, Cc = 15fF, and CCLK = 5fF. Ignore the body effect and calculate the voltage drop on Vo, if (a) Only C changes to 1 (VDD=5.0) during the evaluate phase. (b) Only A changes to 1 (VDD=5.0) during the evaluate phase. (c) Both A and B change to 1 (VDD=4.8V) during the evaluate phase (C remains off). (d) All A, B, and C change to 1 (VDD=3.3V) during the evaluate phase.

Consider the circuit as shown below, assume that all inputs are 0 during the pre-charge phase and all the internal nodes are initially 0 V. Suppose all the nMOS transistors have the same Vtn0 = 0.6 V, 2phiF = 0.5 V, and gamma = 0.35V1/2. With CA = 60fF,CB = 10fF, CC = 10fF, calculate the voltage drop on Vo if: (a) Only B changes to 1 (VDD = 3.0 V) during the evaluation phase. Do not ignore body effect (i.e., don't assume Vsb = 0 V ). (b) Both A and B changes to 1 (VDD=3.0 V) during the evaluation phase. Ignore body effect here (Vsb = 0V) (c) Only A changes to 1 (VDD=3.0 V) during the evaluation phase. Do not ignore body effect.
