Abstract
A data pulse receiver includes a data regenerator and a peak detector, both having set-reset flip-flops (RS-FFs) to generate hysteresis which is varied based on its tail current provided to the RS-FF. The regenerator regenerates data from a differential signal derived from an incoming data signal. The peak detector monitors the peak level of the differential signal derived and its output adjust automatically the tail currents of the data regenerator and the peak detector. The receiver also includes impedance matching networks connected to the data regenerator and the peak detector. The input impedances for both networks are essentially the same. The tail currents for the two RS-FFs of the regenerator and the peak detector are essentially equal and it ensures precise cancellation of non-linear effects.
