Abstract
A differential voltage amplifier having high gain and a wide bandwidth essentially comprises an unstable circuit having one position of unstable equilibrium and two distinct positions of equilibrium which can be maintained for a given period of time, an input stage for applying signals to the input of said unstable circuit for a given period of time, means for returning the unstable circuit to its position of unstable equilibrium, means for calibrating the output of the unstable circuit at the voltage +V.sub.m or at the voltage -V.sub.m according to the position of unstable equilibrium, means for integrating the calibrated signal which appears at the output of the bistable circuit for a given period of time and a clock for the synchronization of the entire circuit.
