Question

Consider the CMOS clocked circuit in Figure (b).

Assume the effective capacitance at the v_O1 terminal is 25 fF.

If the leakage current through the M_{N A} and M_{N B} transistors is ILeakage = 2 pA when these transistors and MP1 are cutoff, determine the time for which v_O1 will decay by 0.5 V.
