Extracted text: 4. Consider the circuit below, which consists of an NMOS device and PMOS current source load. Do not neglect channel length modulation. a) Calculate the width of the PMOS device so its saturation current is 50µA. b) Calculate VM, VOH, VOL. Remember, for hand calculations we assume VOH=VMAX, and VOL=VMIN. c) Calculate the voltage gain of this circuit, when Vin=VM. VDD=1.5V Vbias=0.5V –d W/L=W/1.5 Vout Vin Cload=0.5pF W/L=6/1.5 2 |Page
