Abstract: A method for controlling an envelope shape of an output signal outputted by a driver of a wireless transmitter includes supplying a first voltage level and a second voltage level, generating a filtered envelope reference signal by switching between the first voltage level and the second voltage level, in conjunction with low-pass filtering the transitions between the first voltage level and the second voltage level, generating a driver supply voltage following the filtered envelope reference signal, regulated in a manner adapted to supply the driver, and controlling the envelope shape of the output signal by supplying the driver with the driver supply voltage.
