The output of a CMOS static inverter is given by: Vin + VTp + (VDD - Vin - VTp) - B(Vin V Vout = Vout= Vin - VTn (Vin - Vn)2 - Vn)2 (VDD - Vin - VTp) B for Low input voltage for High input voltage a) Justify the choice of points on the transfer characteristics of an inverter where the slope of Vout versus Vin is -1, to define the input and output logic 'Low' and 'High' levels. b) Evaluate the value of ViL, VOL, ViH and VoH in terms of VDD, VT, VTp using the equations given above, assuming 3 = 1. c) Compare the voltage difference between VDD and VOH with the voltage difference between VoL and ground for 3 = 1, VTn # VTp.
