Abstract:
A receiver has a differential transimpedance amplifier ( 4 ) with two inputs and two outputs. The differential transimpedance amplifier ( 4 ) provides a differential output and this is peak-detected ( 15, 16 ) to provide amplitude reference signals. The differential transimpedance amplifier output and the amplitude reference signals are fed to a differential summing amplifier ( 10 ), which provides a fully differential signal to a comparator, or to an automatic gain control circuit ( 5 ) to regulate the differential transimpedance amplifier gain. The differential summing amplifier ( 10 ) output is a fully differential signal, thereby having lower distortion for DC and burst mode receiver applications.

Claim (Index 1):
An optical receiver comprising:\n a differential transimpedance amplifier TIA having input cascodes, and being arranged to receive one or more photodiode inputs and to provide at least two outputs, positive and negative, a positive peak detector receiving the positive differential TIA output, a negative peak detector receiving the negative differential TIA output, and each providing a peak detection output as an amplitude reference signal, a differential summing amplifier arranged to receive the outputs of the differential TIA and the amplitude reference signals from the peak detectors, wherein said differential summing amplifier directly or indirectly provides an output for the optical receiver, wherein the receiver further comprises an automatic gain circuit for the differential transimpedance amplifier, and wherein the differential summing amplifier is connected at its output to the automatic gain circuit.
