An NMOS pass-transistor switch with W/L= 1.2 um / 0.8 um. used in a 3.3-V system for which Vt0 = 0.8 V,(lambda)= 0.5 V^(1/2), 2(phi)f= 0.6 V , unCox = 3upCox = 75 uA/V^2, drives a 100-fF load capacitance at the input of a matched standard CMOS inverter using (W/L)n = 1.2 um ? 0.8 um. For the switch gate terminal at VDD, evaluate the switch VOH and VOL for inputs at VDD and 0 V, respectively.
For this value of VOH, what inverter static current results? Estimate tPLH and tPHL for this arrangement as measured from the input to the output of the switch itself.
