摘要： A power amplifier (PA) envelope power supply, radio frequency (RF) PA circuitry, and a process to select a converter operating mode of the PA envelope power supply based on linearity requirements of the RF PA circuitry is disclosed. The PA envelope power supply operates in one of a first converter operating mode and a second converter operating mode. The process for selecting the converter operating mode is based on a required degree of linearity of the RF PA circuitry. The PA envelope power supply provides an envelope power supply signal to the RF PA circuitry. Selection of the converter operating mode may provide efficient operation of the PA envelope power supply and the envelope power supply signal needed for proper operation of the RF PA circuitry.

摘要： A direct current (DC)-DC converter having a DC-DC converter semiconductor die and an alpha flying capacitive element is disclosed. The DC-DC converter semiconductor die includes a first series alpha switching element, a second series alpha switching element, a first alpha flying capacitor connection node, which is about over the second series alpha switching element, and a second alpha flying capacitor connection node, which is about over the first series alpha switching element. The alpha flying capacitive element is electrically coupled between the first alpha flying capacitor connection node and the second alpha flying capacitor connection node. By locating the first alpha flying capacitor connection node and the second alpha flying capacitor connection node about over the second series alpha switching element and the first series alpha switching element, respectively, lengths of transient current paths may be minimized, thereby reducing noise and potential interference.
