Abstract
A PA power supply, which includes a first ET power supply, power supply control circuitry, a first PMOS switching element, and a second PMOS switching element, is disclosed. During a first operating mode, the power supply control circuitry selects an OFF state of the first PMOS switching element, selects an ON state of the second PMOS switching element, and adjusts a voltage of a first switch control signal to maintain the OFF state of the first PMOS switching element using a voltage at a source of the first PMOS switching element and a voltage at a drain of the first PMOS switching element; the PA power supply provides a first PA power supply signal; and the first ET power supply provides a first ET power supply signal, such that the first PA power supply signal is based on the first ET power supply signal.
