Programmable continuous time linear equalizer having stabilized high-frequency peaking for controlling operating current of a slicer

A method comprising:

• driving an active load circuit using a differential amplifier, 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
• generating, using a bias circuit, 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, wherein generating the PVT-dependent control voltage comprises tracking the PVT-dependent voltage at the gate of the pair of load transistors using a replica load transistor in the bias circuit, the replica load transistor matched to the pair of load transistors, the PVT-dependent control voltage stabilizing the high frequency peaking of the high-frequency gain stage.
