Abstract
A circuit for adjusting a magnitude of a transmit signal includes a transmitter (), providing a transmit signal (). It also includes a transmitter amplifier (), receiving the transmit signal () and a power control adjustment signal (), and responsive thereto, providing an amplified transmit signal (). The circuit also includes a detector (), for detecting an amplitude of the amplified transmit signal (). Also included is an error component () for determining the difference between the amplitude and a reference level (). Further provided is a digital signal generator (), receiving the difference (), and responsive thereto, generating () a reference signal () and the power control adjustment signal (), where the reference level () is responsive to the reference signal ().
