  • Pulse light-receiving circuit with means to minimize power source noise
    Patent number: 5498993
    Abstract: A pulse light-receiving circuit includes a pair of preamplifiers made up of the same circuit components, a difference amplifier for amplifying the outputs from the preamplifiers, and a pair of peak value-detecting circuits made up of the same circuit component for obtaining the amplitude of an input pulse signal. The median of that amplitude is used as a reference voltage for comparison with an output from the difference amplifier.
