Figure 1 shows an 18 nm NMOS finFET switch. The slow regime ofcharge injection is valid for this circuit. Assume Vin = 0.5 V,nfin = 10 and CL = 20 fF. The body of the transistor is connectedto ground, VB = 0 V. It is safe to ignore the body effect (? =0).Initially the charge on CL is zero. Calculate Vout at t1 for thegate pulse shown in Figure 1.

Problem 1. Figure 1 shows an 18 nm NMOS finFET switch. The slow regime of charge injection is valid for this circuit. Assume Vin = 0.5 V, nfin = 10 and CL = 20 fF. The body of the transistor is connected to ground, V = 0 V. It is safe to ignore the body effect (x =0). Initially the charge on CL is zero. Calculate Vout at ti for the gate pulse shown in Figure 1.
