Voltage distribution for controlling cmos rf switch

A tangible computer-readable medium having stored thereon computer-executable instructions that, if executed by one or more computing devices, cause the one or more computing devices to perform operations comprising:

• determining whether to amplify a radio frequency (RF) signal by a first gain or a second gain, the first gain achievable by a first circuit having one or more power amplifiers and configured to be turned on or off by a triple-well CMOS switch having an isolated well about the switch's source and drain, and an isolation well about the isolated well, the switch in the on state resulting in the RF signal being amplified by the first gain, and the switch in the off state resulting in the RF signal being amplified by the second gain;
• and
• generating a control signal for application of bias voltages to the switch, the control signal formatted so as to allow application of different bias voltages for the on and off states of the switch to at least one of the isolated and isolation wells.

A system for amplifying radio frequency signals, the system comprising:

• a means for amplifying a radio frequency (RF) signal so as to provide first and second gains;
• a means for switching a complementary metal oxide semiconductor (CMOS) switch between first and second states, the switch comprising source and drain, a gate between the source and the drain, and a first well formed about the source and drain, the switch configured to be capable of being in the first and second states so as to facilitate the amplification of the RF signal by the first and second gains;
• a means for distributing different bias voltages for the first and second states of the switch to at least one of the first and second wells.
