THE DIGITAL LOGIC INVERTER
Transition region
Operation is described by voltageTransfer characteristic (VTC).
VIL –max value for for input interpreted
as logic zero
VIH –max value for for input interpreted
as logic oneNoise margins 1-1
The Ideal VTC
Ideal inverter maximizes noise marginsAnd distributes them equally between The low and high regions.(No transition region.)
