The present invention comprises a dynamic front end radio receiver that determines the current operating conditions and adjusts the power consumption of the receiver accordingly. In one embodiment, the receiver can detect the strength of an incoming signal and the presence of any interfering signals. The receiver includes a series of programmable blocks, where the bias of each block is adjustable. The power consumption of the overall receiver can be minimized by controlling each programmable block with a control signal. Thus, the receiver can contend with a dynamic environment, so that the performance is controlled in a manner sufficient to process the incoming signal and minimize the power dissipation necessary to achieve acceptable radio performance. An embodiment of the invention may be used in wireless radio networks for a variety of applications, such as healthcare wireless technology. |
