摘要
Methods and systems for peak detection as part of automatic gain control in high-speed communications are provided. A peak detection system uses a portion of an input signal to generate a reference signal for comparison with the input signal. The comparison produces a differential error signal that is in turn used to produce one or more full swing pulses based on the comparison. A pulse counter counts the pulses, and if the count in a single clock cycle is above a determined threshold, a binary error signal is set to indicate a need for correction.
