Abstract
A bistable circuit includes a first inverter and a capacitive inversion circuit having one input coupled to an output of the first inverter. The capacitive inversion circuit includes a second inverter and a capacitive circuit parallel-coupled to the input and an output of the capacitive inversion circuit. The bistable circuit also includes a switch to isolate the output of the capacitive inversion circuit from an input of the first inverter when the switch receives an active validation signal or, if not, to couple the output of the capacitive inversion circuit to the input of the first inverter.
