Abstract:
Embodiments of a power amplifier and method of operating a power amplifier are disclosed. In one embodiment, a power amplifier includes a pulse wave modulation (PWM) controller, a first power control stage configured to drive a first output between VDD and VSS in response to a control signal from the PWM controller, a second power control stage configured to drive a second output between VDD and VSS in response to a control signal from the PWM controller, and a mid-voltage control circuit configured to hold the voltage of the first output at a mid-voltage that is between VDD and VSS during an interval between when the first output is driven between VDD and VSS and hold the voltage of the second output at the mid-voltage during an interval between when the first output is driven between VDD and VSS.
