摘要
Active load circuit-The active load circuit performs high frequency peaking for the active load circuit according to the frequency response characteristic determined in part by the resistance value of the pair of active resistors respectively connected to the gates of the pair of load transistors and the pair of load transistors. It has a high-frequency gain stage that provides-a differential amplifier that drives and the active resistor to stabilize the resistance value of the pair of active resistors that will be responsible for the process and temperature fluctuation (PVT) dependent voltage at the gate of the pair of load transistors. A method and system is described that includes a bias circuit configured to stabilize the high frequency peaking of the high frequency gain stage by generating a PVT dependent control voltage at the gate.
