Abstract
An electronic device may include wireless circuitry with a processor, a transceiver, an antenna, and a front-end module coupled between the transceiver and the antenna. The front-end module may include one or more power amplifiers for amplifying a signal for transmission through the antenna. A power amplifier may include a phase distortion compensation circuit. The phase distortion compensation circuit may include one or more n-type metal-oxide-semiconductor capacitors configured to receive a bias voltage. The bias voltage may be set to provide the proper amount of phase distortion compensation.
