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