Abstract
An apparatus including a bias voltage generator and one or more cascode drivers. Each of the one or more cascode drivers may include a plurality of cascode transistors. The bias voltage generator may control the cascode bias voltages provided to the cascode transistors based on a plurality of programmable control bits received by the bias voltage generator. The received plurality of programmable control bits may include a first set of programmable control bits, which may be used to control the magnitude of the cascode bias voltages, and a second set of programmable control bits, which may be used to control the stability of the cascode bias voltages.
