ABSTRACT:
A method for enlarging part of an analog input signal, and a circuit to implement this method. The circuit includes an amplifier which receives the analog input signal, the gain of which is controlled by a programming signal which varies as a function of the leading edge of the analog input signal and of a maximum threshold of the output signal from the circuit. A subtractor receives a substraction signal which is a function of an upper threshold and a lower threshold of the output signal from the circuit, and a signal from the amplifier, and then provides the output signal from the circuit.
