Abstract
A method for startup and operation of an output stage of a transmitter, the output stage comprising a first protection field effect transistor (FET) and a second protection FET includes enabling a startup circuit; providing a first bias voltage to the first protection FET in the output stage and a second bias voltage to the second protection FET stage in the output stage by the startup circuit; disabling the startup circuit and enabling a protection voltage generator; providing the first bias voltage to the first protection FET in the output stage by the protection voltage generator; and providing the second bias voltage to the second protection FET in the output stage by a second bias voltage power supply.
