Question

Quiz# 5 & 6: Intro to VLSI Design Name: Use Cadence to find the VTC (Voltage Transfer Characteristics) plot for a CMOS inverter to get Vout Vs Vin. From those plots find the NMi. and NMH for following two W/L ratio: 1. a. Both nMOS and pMOS transistor with same W/L: 1.5 μm /06μm b. Both nMOS and pMOS transistor with same W/L: 15 μm /0.6μm
