Abstract

The present is proposed a low power RF-transceiver included a receiver and a transmitter. A gain amplifier and a supper regenerative divider construct an RF receiver; a voltage controlled oscillator (VCO) and a one stage power amplifier (PA) consist an RF transmitter. The digital modulation, binary frequency shift-keying (BFSK), is employed to modulate a wireless communication signal for proposed interactive intelligent healthcare monitoring system (IIHMS). The gain amplifier of RF receiver is biased in sub-threshold region for low power application. The proposed RF transceiver implemented in TSMC 0.18-μm 1P6M standard CMOS process with a chip area of 2.47 mm2. The measurement results show that the power consumption of the RF transmitter and receiver are 2.34 mW and 1.26 mW, respectively, under the lower supply voltage of 1.2 V.
