摘要： A charge pump of a power amplifier (PA) bias power supply and a process to prevent undershoot disruption of a bias power supply signal of the PA bias power supply are disclosed. The charge pump operates in one of multiple bias supply pump operating modes, which include at least a bias supply pump-up operating mode and a bias supply bypass operating mode. The process prevents selection of the bias supply pump-up operating mode from the bias supply bypass operating mode before charge pump circuitry in the charge pump is capable of providing adequate voltage to prevent undershoot disruption of the bias power supply signal.

摘要： At least a first shunt switching element and switching control circuitry of a first switching power supply are disclosed. At least the first shunt switching element is coupled between a ground and an output inductance node of the first switching power supply. The first switching power supply provides a buck output signal from the output inductance node. The switching control circuitry selects one of an ON state and an OFF state of the first shunt switching element. When the buck output signal is above a first threshold, the switching control circuitry is inhibited from selecting the ON state. The first switching power supply provides a first switching power supply output signal based on the buck output signal. By using feedback based on the buck output signal, the switching control circuitry may refine the timing of switching between series switching elements and shunt switching elements to increase efficiency.

摘要： A direct current (DC)-DC converter and radio frequency (RF) power amplifier (PA) circuitry are disclosed. The DC-DC converter provides an envelope power supply signal to the RF PA circuitry based on a first power supply output control signal. As a temperature of the RF PA circuitry changes, the envelope power supply signal may need to be adjusted to meet temperature compensation requirements of the RF PA circuitry. With adequate thermal coupling between the DC-DC converter and the RF PA circuitry, adjustments to the envelope power supply signal may be based on temperature measurements of the DC-DC converter. A desired correction of the first power supply output control signal is determined based on a measured temperature of the DC-DC converter and the temperature compensation requirements of the RF PA circuitry. The first power supply output control signal is adjusted based on the desired correction.

摘要： Power amplifier (PA) control circuitry and PA bias circuitry are disclosed. During one slot of a multislot transmit burst from radio frequency (RF) PA circuitry, the PA control circuitry selects one PA bias level of the RF PA circuitry and the RF PA circuitry has one output power level. The RF PA circuitry has a next output power level during an adjacent next slot of the multislot transmit burst. If the one output power level exceeds the next output power level by more than a power drop limit, then the PA control circuitry maintains the one PA bias level during the adjacent next slot. If the one output power level significantly exceeds the next output power level, but by less than the power drop limit, then the PA control circuitry selects a next PA bias level, which is less than the one PA bias level, during the adjacent next slot.

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.
