Abstract: Embodiments of circuitry, which includes power supply switching circuitry, a first inductive element, and a second inductive element, are disclosed. The power supply switching circuitry provides a first switching output signal to the first inductive element and a second switching output signal to the second inductive element. The first inductive element has a first inductor current and the second inductive element has a second inductor current. The second switching output signal is delayed from the first switching output signal by a switching signal delay. The first inductor current and the second inductor current combine to provide a combined inductor current, which has a frequency response with a group of notches, such that frequency locations of the group of notches are based on the switching signal delay.

Abstract: An RF communications system, which includes an RF power amplifier, an envelope tracking power supply, and supply control circuitry, is disclosed. The RF communications system operates in one of a normal operation mode and a calibration mode. During the calibration mode, the RF power amplifier receives and amplifies an RF input signal to provide an RF transmit signal using an envelope power supply signal, which is provided by the envelope tracking power supply. Further, the supply control circuitry controls the envelope tracking power supply to cause a sharp transition of the envelope power supply signal when a setpoint of the envelope power supply signal transitions through a setpoint threshold of the envelope power supply signal.
