Light signal amplification and processing circuit

摘要

The circuit uses a photocurrent amplifier (2) for amplification of the light signals, providing 2 outputs with a constant sum current and a difference current proportional to the received light signal. A regulating circuit (6,10,12,15,16,17) provides an offset current or offset voltage regulation within a given time interval from activation of the photocurrent amplifier to provide a constant output (14), the output signal characteristic conforming to the light signal within a second time interval, corresponding to the duration of the light signal.
