“…In this study, we mainly focus on the BF-WSN that harvests radio signal energy. Although the energy harvested from radio signals is on the scale of nJ, the BF-WSN is promised to be widely applied because ultra-low power transceivers have been born [11].…”

“…Generally, the RF transceiver is comprised of the low noise amplifier (LNA), mixer, band-pass filter, IF amplifier, power amplifier (PA), frequency synthesizer, and several other circuit modules. Several methods have been proposed to improve the traditional transceiver structure by integrating multiple functions in one module or reusing bias current in multiple modules [3][4][5][6][7]. For each module in the transceiver, the traditional design optimization theory is mainly aimed at the improvement of circuit performance while less consideration is given to power saving [8][9][10][11][12].…”

This paper presents a low-voltage ZigBee transceiver covering a unique frequency band of 780/868/915/2400 MHz in 180 nm CMOS technology. The design consists of a receiver with a wideband variable-gain front end and a complex band-pass filter (CBPF) based on poles construction, a transmitter employing the two-point direct-modulation structure, a Ʃ-Δ fractional-N frequency synthesizer with two VCOs and some auxiliary circuits. The measured results show that under 1 V supply voltage, the receiver reaches −93.8 dBm and −102 dBm sensitivity for 2.4 GHz and sub-GHz band, respectively, and dissipates only 1.42 mW power. The frequency synthesizer achieves −106.8 dBc/Hz and −116.7 dBc/Hz phase noise at 1 MHz frequency offset along with 4.2 mW and 3.5 mW power consumption for 2.4 GHz and sub-GHz band, respectively. The transmitter features 2.67 dBm and 12.65 dBm maximum output power at the expense of 21.2 mW and 69.5 mW power for 2.4 GHz and sub-GHz band, respectively.
