Abstract
A one-shot state machine circuit, preferably implemented exclusively with CMOS transistors, converts long state changes to pulses or one-shots with a fixed duration. A short signal stage to eliminate responses to short glitch signals and a majority gate inside an input state provide the one-shots in response to valid input signals. An output stage mediates conflicting signals from the short signal stage and the majority gate.
