A low-power transceiver for ISM applications in the 868-MHz band has been integrated in a 0.8-/spl mu/m BiCMOS technology. The receiver part is based on the super-regenerative principle. The system includes two time-shared control loops, one for the selectivity and sensitivity control and one for the frequency control (PLL). The receiver with its PLL draws 3.6 mW for a sensitivity of -105 dBm and the emitter current consumption is 6 mA for a 0-dBm output power. A 2.4-V operation voltage allow the use of a two-batteries solution.
