Description
This applet demonstrates the static two-input and three-input NOR gates in CMOS technology. Click the input switches or type the ('a','b') and ('c','d','e') bindkeys to control the gates.
The three-input NOR3 gate uses three p-channel transistors in series between VCC and gate-output, and the complementary circuit of a parallel-connection of three n-channel transistors between GND and gate-output.
NOR3 A B C | Y -----------+---- 0 0 0 | 1 0 0 1 | 0 0 1 0 | 0 0 1 1 | 0 1 0 0 | 0 1 0 1 | 0 1 1 0 | 0 1 1 1 | 0
