MOSFET and resistor NOR gate PUBLIC

Two n-channel MOSFETs plus one pull-up resistor form a two-input NOR logic gate.

When both A or B are high, the output voltage is pulled low by M1 and/or M2. Otherwise, the output voltage is high.

A few things to try in CircuitLab

Load the simulation by clicking "Open in editor" above, and then click "Simulate" at the bottom. Run a time domain simulation.

Verify digital operation

Plot A, B, and out versus time. You should verify that the logic performs the correct operation.

Power consumption

How much current is consumed when the output is in the low state?
