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 6mA for a 0-dBm output power. A 2.4-V operation voltage allow the usage of a two-batteries solution.1 GHz2.4 V3.6 mW6 mABiCMOS technologyLNAamplitude controldemodulationdifferential pairemitter current consumptionenvelope detectionfrequency controllow-power transceiveron-off keying binary signalsperiodically tuned oscillatorselectivity controlsensitivity controlsuper-regenerative transceivertime-shared PLL controltime-shared control loopstiming diagramtwo-batteries solutionBiCMOS analogue integrated circuitsUHF integrated circuitsUHF oscillatorscircuit tuningdemodulatorsfrequency controllow-power electronicsphase locked loopsphase locked oscillatorstransceiverstext::journal::journal article::research article
