Abstract
A progressive envelope tracking (ET) with delay compensation includes an ET integrated circuit (IC) (ETIC) that is a progressive ETIC that switches between different driver amplifiers having different associated offset voltages based on a tracking signal (e.g., Vramp) from a baseband transceiver. To make sure that desired changes to the offset voltage occur contemporaneously with an input signal for the driver amplifiers, a delay may be added to the input signal for the driver amplifiers. By adding and controlling this delay to the input to the driver amplifiers, the changes to the offset voltage will track the changes to the input signal at the driver amplifiers and overall efficiency of the ETIC may be improved.
