Summary:An envelope tracking supply modulator includes an amplifier circuit and a zero peaking circuit. The amplifier circuit receives an envelope input, generates a modulated supply voltage according to the envelope input, and provides the modulated supply voltage to a power amplifier. The zero peaking circuit is coupled to the amplifier circuit, and applies zero peaking to the amplifier circuit, where the zero peaking inserts a zero at a frequency.
