Abstract: An adaptive current control circuit for reduced power consumption and minimized gain shift in a variable gain amplifier.

The ratio of PTAT current and CTAT current is adjustable for specific temperature ranges to further minimize temperature effects on the gain.

Abstract: The present invention provides architectures and methods which use multiple radio receive chains in mobile devices to boost performance of the mobile devices. While a first set of the receive chains are assigned to a serving base station, another set of receive chains are dynamically allocated to neighbor base stations and/or to the serving base station depending upon present or expected system conditions and timing. A first synthesizer is configured to provide signals to the first and second set of receive chains. Other synthesizers are also configured to provide signals to the second set of receive chains. Thus, depending on the mode of operation, the second set of receive chains utilizes signals from a given synthesizer as needed. A priori data may be used to allocate specific receive chains to the serving base station, neighboring base stations or both. Unused synthesizers may be turned off to conserve power.
