Popis: This letter presents a 2.4-GHz sliding-IF ZigBee receiver front end for wireless sensor networks. The receiver targets extreme high energy efficiency by sharing its power between all RF blocks. It employs a 0-V supply passive gain booster and mixers combo with its power coupled from the voltage-controlled oscillator (VCO) by using the transformer coupling technique. The quasi-passive mixer and quadrature passive mixer down converts the RF signal to the baseband without need of the dc supply voltage. The VCO achieves a phase noise of −110 dBc/Hz at 1 MHz while dissipating $580~\mu \text{W}$ . The RF front end demonstrates the conversion gain of 13.5 dB, noise figure of 6.1 dB, and IIP3 of −9.4 dBm at the frequency band of 2.41–2.53 GHz.
