A NOR has parallel N's, but the Ps are in-series. A single N can discharge the output capacitance. It takes all three Ps to charge the output capacitance. If the ON resistance of an N is 100Ω, what would the ON resistance of a P have to be so that the charge/discharge times are equal?Question:
Design a 3-input NOR gate. If the PMOS devices are half as conductive as the NMOS devices determine the correct transistor sizes.
I understand how to design the pull up pull down circuit, just unsure about calculating the correct transistor sizes. Thanks
