Power amplifier and method of operating a power amplifier

A power amplifier comprising:

• 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 comprising:
• a first switch connected to the first output 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;
• a second switch connected to the second output to hold the voltage of the second output at the mid-voltage during an interval between when the second output is driven between VDD and VSS;
• and
• a voltage holding circuit connected between the first and second switches of the mid-voltage control circuit.
