Abstract
The present disclosure is directed to a light-signal communication receiver device including a photo-receiving diode configured to generate a current signal on a first node from a received light signal, a preamplifier configured to convert the current signal on the first node into a voltage signal on a second node, and a differential amplifier including a first input connected to the first node and a second input connected to a third node coupled to the second node via an adjustment circuit. The adjustment circuit is configured to offset the level of the voltage signal of the second node, on the third node, in a controlled manner by a control signal.
