• A fully integrated 2.4 GHz CMOS RF transceiver with short range wake-up function for low-rate wireless personal area network (LR_WPAN) applications in a 0.18-mum CMOS technology is implemented and measured. The chip fully complies with the IEEE 802.15.4 standard. The single chip transceiver incorporates an I/Q modulator and demodulator, an integrated RF synthesizer with a stacked voltage controlled oscillator (VCO), a receiver including the antenna diversity, and passive wake-up circuits using rectifiers. The power consumption in the active and sleep mode is improved by using a passive wake-up circuits and a stacked VCO. The transmitter achieves less than 5.0% error vector magnitude (EVM) at 2 dBm output and the receiver sensitivity is -95 dBm. The sensitivity of the wake-up block is -29.8 dBm. The current consumption is under 14.3 mA for data receiving mode, 16.7 mA for transmitter and less than 800 nA for sleep mode from a 1.8 V power supply.
