1. Voltage transfer characteristics (VTC) of a resistor load inverter by using enhancement type nMOS transistor is given in Figure 1. Vout(V) 4 1 Vin(V) 0. 1 2 3 4 Figure 1 Assume that this inverter is supplied with Vpp = 5 V and the parameters of this transistor is k 45 A/V?, Vro = 0.6 V and channel length L = 1.5 um. %3D (a) Determine VoL by using VTC graph given in Figure 1. (b) Determine resistor (R,) and channel width (W) values by using Vol obtained in (a) where DC power consumption of this inverter is less than 300 W.
