Abstract
A multi-voltage biasing system with over voltage protection has an amplifier with a stage including at least one output device and one cascode protection device having a predetermined maximum recommended voltage; a biasing network is selectively responsive to a plurality of different supply voltages at least one of which is higher than the maximum recommended voltage for providing to the stage a bias voltage to operate the cascode device and output device below their maximum recommended voltages.
