摘要
Methods and systems are described that include a differential amplifier driving an active load circuit, the active load circuit having a pair of load transistors and a high-frequency gain stage providing high frequency peaking for the active load circuit according to a frequency response characteristic determined in part by resistive values of a pair of active resistors connected, respectively, to gates of the pair of load transistors, and a bias circuit configured to stabilize the high frequency peaking of the high-frequency gain stage by generating a process-and-temperature variation (PVT)-dependent control voltage at gates of the active resistors to stabilize the resistive values of the pair of active resistors to account for PVT-dependent voltages at the gates of the pair of load transistors.
