Abstract
An error amplifier providing an analog error signal, including an operational amplifier, an output terminal of which controls an active load of discharge of a resistive and capacitive network supplied by a reference current source, and circuitry for copying the reference current in an input resistor, a terminal of which receives a measurement signal and the other terminal of which is connected to a non-inverting input of the operational amplifier, the error signal being available across the resistive and capacitive network.
