Abstract
A circuit including: an optical detector for detecting an optical pulse and generating therefrom a current pulse on an output; a pulse detector circuit having an input electrically connected to the optical detector and having an output for outputting a detection pulse in response to detecting the current pulse on its input, said pulse detector circuit including: a resettable amplifier including an input for receiving the current pulse from the optical detector, a reset terminal for resetting the amplifier after the amplifier detects the current pulse on its input, and an output for outputting a signal from which the detection pulse is derived; and a reset delay chain feeding back to the reset terminal of the resettable amplifier a feedback signal derived from the output signal of the resettable amplifier.
