Abstract: A wireless transceiver. The transceiver includes: (i) a transmit signal path; (ii) a calibration path, comprising a conductor to connect a calibration tone into the transmit signal path; (iii) a receive signal path, comprising a first data signal path to process a first data and a second data signal path, different than the first data signal path, to process a second data; (iv) a first capacitive coupling to couple a response to the calibration tone from the transmit signal path to the first data signal path; and (v) a second capacitive coupling to couple a response to the calibration tone from the transmit signal path to the second data signal path.

Abstract: Disclosed embodiments of a power converter include a power output stage for generating a first voltage output and an auxiliary power output stage for generating a second voltage output. The power converter further includes a pulse frequency modulation (PFM) controller for controlling the power output stage in response to the first voltage output generated by the power output stage during a first period of time in which the power output stage operates in a PFM mode, and a pulse width modulation (PWM) controller for controlling the auxiliary power output stage in response to the second voltage output generated by the auxiliary power output stage during a second period of time. At least a portion of the first period of time is concurrent with the second period of time.

Abstract: A power stage for a DC-to-DC voltage converter includes a voltage input, a high-side n-channel transistor, a high-side p-channel transistor, and a low-side n-channel transistor. The voltage input is couplable to a supply voltage. The drain terminal of the high-side n-channel transistor is coupled to the voltage input and the source terminal is coupled to a first node that is couplable to an output stage of the DC-to-DC converter. The source terminal of the high-side p-channel transistor is coupled to the voltage input and the drain terminal is coupled to the first node. The drain terminal of the low-side n-channel transistor is coupled to the first node and the source terminal is coupled to a ground.

Abstract: A power conversion system includes, for example, a PFM controller, a PWM controller, and an auxiliary voltage output stage. The PFM controller controls a power output stage in a PFM mode in response to a power stage voltage output generated by the power output stage during a first period of time in which the power output stage is operating in the PFM mode. The PWM controller controls the power output stage in a PWM mode in response to a power stage voltage output generated by the power output stage during a second period of time in which the power output stage is operating in the PWM mode. The auxiliary voltage output stage generates an auxiliary voltage during a third period of time, where the PWM controller controls the auxiliary power output stage using the auxiliary voltage during the third period of time.
