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 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.

摘要： The present disclosure describes a distributed amplifier (DA) that includes active device cells within sections that are configured to provide an input gate termination that is conducive for relatively low noise and high linearity operation. A section adjacent to an output of the DA is configured to effectively terminate the impedance of an input transmission line of the DA. Each active device cell includes transistors coupled in a cascode configuration that thermally distributes a junction temperature among the transistors. In this manner, noise generated by a common source transistor of the cascode configuration is minimized. The transistors coupled in the cascode configuration may be fabricated using gallium nitride (GaN) technology to reduce physical size of the DA and to further reduce noise.

摘要： An apparatus comprises at least one transmit amplifier and rectification circuitry located in the at least one transmit amplifier, which is configured to receive a RF signal and provide a rectified voltage, which is selectably added to a voltage supplied by a battery to generate a DC voltage supply signal that is a function of RF power level. A controller is configured to select between providing the VBAT or the VSupply signal to a transmit switch depending on one or more of a logic state and a mode of operation. An alternate apparatus comprises a charge pump circuit configured to quickly raise a voltage supplied to it and store the output voltage on a capacitor and then either shift a first frequency provided by a charge pump oscillator to a lower second frequency or turn off a charge pump clock to maintain a voltage on the capacitor during a transmit mode.

摘要： The present disclosure relates to down conversion circuitry that uses a fast DC correction method to correct for a DC offset of an RF mixer and a post mixer amplifier. The down conversion circuitry may include a DC correction amplifier downstream of the post mixer amplifier to apply a DC correction, which is based on a gain of the post mixer amplifier. During a calibration mode, the DC offset of the RF mixer and the post mixer amplifier are determined at multiple gain levels of the post mixer amplifier. The DC correction needed at multiple gain levels of the post mixer amplifier is then determined based on the determined DC offset. During a normal operation mode, a desired gain of the post mixer amplifier is selected and a determined DC correction that correlates with the desired gain is provided.
