Given the following circuit, assuming that all inputs of the circuit shown in Figure 1 below are initially 0 during the precharge phase and that all internal nodes are at 0V: a. Calculate the voltage drop on V0, if A changes to 1 (VDD = 2.5 V) during the evaluate phase. It is given that Vtn = 0.5 V, 2φF = 0.6 V and γ = 0.4 V0.5 . Hint: Don’t forget the body effect. b. Now calculate the voltage drop on Vo if both A and B change to 1 (under the above conditions). c. What is the maximum number of transistors that can be connected in series to M1 and M2 (including M1 and M2, excluding M0 ) if the output should not fall below 0.9 V during the evaluate phase? Assume that each one of the new transistors has the same intrinsic capacitance (to ground) as M1 and M2 (C=10fF).

Charge sharing is an important problem in dynamic circuits. Switching exposes a fixed amount of charge to a different capacitive environment. This results in node voltage change. After pre-charge stage, the output node voltage of the dynamic logic circuit in Figure 1 will be equal to VDD. During the evaluate phase, assume A = 1 and B=0. Output node will not connect to ground but the total charge on the output node (Q = C.V) will be shared by parasitic capacitance (C1) and the load capacitance (CL). So that the output voltage will drop and be equal to M1 source voltage. a. The circuit is Figure 1 is pre-charged with VDD = 3V. During evaluation stage, M1 turns on and M2 is off (A=1 and B=0). CL = 250fF, C1 = 125fF and Vt0,n=0.55V. Calculate the final voltage after charge sharing. Is M1 still conducting at this voltage? b. Repeat question a for C1 = 40fF. Calculate the final voltage after charge sharing. Is M1 still conducting at this voltage? If not, what is the value of the output voltage at this scenario? c. With A = 1 and B = 0, the output of the circuit in Fig 1 should be logic high. However, you have seen that logic high does not mean VDD for this example. Output voltage depends on the parasitic capacitance at the source node of M2. For a dynamic 2 input NAND gate, what is the maximum value that the Figure 1 output voltage can reach when A= 1 and B = 0?
