Answer Posted / iqra

The threshold voltage of a MOSFET is usually defined as the
gate voltage where an inversion layer forms at the
interface between the insulating layer (oxide) and the
substrate (body) of the transistor

Calculate rise delay of a 3-input NAND gate driving a 3-input NOR gate through a 6mm long and 0.45m wide metal wire with sheet resistance R = 0.065 / and Cpermicron= 0.25 fF/m. The resistance and capacitance of the unit NMOS are 6.5k and 2.5fF. Use a 3 segment -model for the wire. Consider PMOS and NMOS size of reference inverter as 2 and 1 respectively. Use appropriate sizing for the NAND and NOR gate.
