Abstract

A partial envelope tracking (PET) circuit for improving the dynamic range and the efficiency of a power amplifier amplifying high bandwidth signals is provided. The PET circuit includes a main supply path having a main valve (MV) connecting the power amplifier to a first power source; a storage capacitor connecting a junction node and the power amplifier; a supplementary supply path including a DV and a TV, each of the DV and the tracking valve connecting, in parallel between a second power source and the junction node; a supplementary current path including a GV connecting the junction node and a ground; and a valves control unit (VCU) configured to monitor an envelope tracking parameter to determine an operation mode of the circuit and a state of each of the MV, the GV, the DV, and the TV during each respective mode of operation.
