A current pulse receiving circuit suitable for converting a current pulse converted by a photodetector from a light pulse received in optical communications and outputting a logic level voltage pulse with an accurate pulse width is disclosed. When an output signal from a current-to-voltage converter circuit is detected to have a large amplitude by a large signal detection circuit, an amount of offset cancellation of a DC cancellation circuit is decreased to limit the amplitude of the output signal from the current-to-voltage converter circuit. Since the ...
1. A current pulse receiving circuit comprising:a current-to-voltage converter portion that converts an input current pulse to a voltage pulse; a comparator circuit that compares as an input signal an output signal from the current-to-voltage converter portion with a signal complementary to the output signal or a reference voltage and outputs a logic signal pulse; a first hysteresis circuit that sets a hysteresis voltage of a first predetermined width to the input signal to the comparator circuit based on the logic signal pulse output therefrom; and, a s...
