Time to discharge the output of a CMOS inverter from Vpp to VOL is given by 2(VDD - Vin + VTn) (Vin - VTn) 2(Vin - VTn) - VOL VOL KnTfall C 1 (Vin - VTn) Here C is the total capacitance given by CL +Cp, where C is the load capacitance from the next stage = 20fF. Cp is the parasitic capacitance due to this stage itself, which is given by Cp = aWn with a = 10fF/um. (1 fF = 10-15F). The channel length is 0.2m for both n and p channel transistors. + In Using the model and device parameters at the end of this paper, find the width for the nMOS transistor such that the output will discharge from VDD to VTn in 100 ps with the input voltage at 1.6V.
