18.6 An NMOS pass-transistor switch with W/L = 130 nm/65 nm, used in a 1-V system for which Vt0 = 0.35 V, γ = 0.25 V1/2, 2ϕf = 1.0 V, μnCox = 3μpCox = 450 µA/V2, drives a 10-fF load capacitance at the input of a matched standard CMOS inverter using (W/L)n = 130 nm/65 nm. 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.
VOH = 0.59 V; VOL = 0V; iDP(VOH) = 1.08A; tPLH = 51.6 ps; tPHL = 27.0 ps
