Abstract:
1. A communication receiver comprising: a data receiver receiving at least one pulse-position modulated signal; a clock circuit separating a reference clock signal into a plurality of coordinating clock signals; a plurality of time integrators gated to generate a plurality of time-integrated signals in response to said at least one pulse-position modulated signal and said plurality of coordinating clock signals; a combiner forming a demodulated signal from said plurality of time-integrated signals; a first transimpedance amplifier converting said reference clock signal from being in the form of a current signal into a first voltage swing signal; and a second transimpedance amplifier converting said at least one pulse-position modulated signal from being in the form of a current signal into a second voltage swing signal; wherein said combiner sums at least a portion of said plurality of time-integrated signals to form said demodulated signal.
