An exemplary embodiment of the present invention described and shown in the specification and drawings is a transceiver with a receiver, a transmitter, a local oscillator (LO) generator, a controller, and a self-testing unit. All of these components can be packaged for integration into a single IC including components such as filters and inductors. The controller for adaptive programming and calibration of the receiver, transmitter and LO generator. The self-testing unit generates is used to determine the gain, frequency characteristics, selectivity, noise floor, and distortion behavior of the receiver, transmitter and LO generator. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or the meaning of the claims.

Adaptive radio transceiver

An embedded processor system including at least one gated power unit including an internal ROM and a power controller that provides one or more gated power signals to selectively provide power to each gated power unit. The power controller provides a gated clock signal to the embedded processor to selectively control power consumption of the processor. The power controller powers down each gated power unit after freezing the processor and then powers up each gated power unit before reactivating the processor. The embedded processor system may include isolation circuitry, such as clamp circuitry or the like, that is operative to minimize current flow into each gated power unit when powered down. The gated power units may include a static function. The ROM of an embedded ROM-based microprocessor system is powered down when the microprocessor is idle to reduce or otherwise eliminate intrinsic leakage.
