ABSTRACT:
A data pulse receiver for detecting and amplifying serial data pulses received at gigabit-per-second rates over a transmission medium through which the signal levels have been substantially attenuated. The receiver, in a preferred embodiment, has grounded base differential amplifiers to give impedance matching, signal amplification and wide frequency bandwidth. A regenerative flip-flop with programmable tail current provides hysteresis in order to suppress unwanted noise signals. The flip-flop also returns the data pulses to NRZ format. The receiver may also include means for automatic adjustment of the hysteresis level.
