Low power RF design for sensor networks

The design of RF circuits for short-range, low-power wireless communication is discussed. A derivation of optimum link range and transceiver power budget is presented based on simple models for indoor path loss and power vs. performance tradeoffs in a generic transceiver. Design techniques aimed at efficiently reaching these parameters are discussed for individual circuit blocks. Finally, some published transceivers are discussed with respect to the optimization and design techniques presented.
