“…There exist many technical challenges in the implementation of a low-power and low-cost reconfigurable dual-band transceiver. Firstly, previously reported transceivers for short range wireless communications mainly only support the single-band operation [7]- [10], or sacrifice some performance with one wideband TRX path to cover dual bands [10]- [11]. In these transceivers, the active Gilbert cells are employed to realize the frequency conversion [8]- [9], [11]- [12], which limits the linearity and 1/f noise performance, and the out-of-band (OB) interference rejection issue in the receiver is also neglected.…”

Permission from IEEE must be obtained for all other users, including reprinting/ republishing this material for advertising or promotional purposes, creating new collective works for resale or redistribution to servers or lists, or reuse of any copyrighted components of this work in other works.A fully-integrated reconfigurable dual-band (760-960 MHz and 2.4-2.5 GHz) transceiver (TRX) for short range wireless communications is presented. The TRX consists of two individually-optimized RF front-ends for each band and one shared power-scalable analog baseband. The sub-GHz receiver has achieved the maximum 75 dBc 3rd-order harmonic rejection ratio (HRR3) by inserting a Q-enhanced notch filtering RF amplifier (RFA). In 2.4 GHz band, a single-ended-to-differential RFA with gain/phase imbalance compensation is proposed in the receiver. A ???? fractional-N PLL frequency synthesizer with two switchable Class-C VCOs is employed to provide the LOs. Moreover, the integrated multi-mode PAs achieve the output P1dB (OP1dB) of 16.3 dBm and 14.1 dBm with both 25% PAE for sub-GHz and 2.4 GHz bands, respectively. A power-control loop is proposed to detect the input signal PAPR in real-time and flexibly reconfigure the PA's operation modes to enhance the back-off efficiency. With this proposed technique, the PAE of the sub-GHz PA is improved by x3.24 and x1.41 at 9 dB and 3 dB back-off powers, respectively, and the PAE of the 2.4 GHz PA is improved by x2.17 at 6 dB back-off power. The presented transceiver has achieved comparable or even better performance in terms of noise figure, HRR, OP1dB and power efficiency compared with the state-of-the-art

“…However, in the receiver the spread sequence has to be locally generated as a reference to synchronize the received signal which will take extra time [11], preventing the extreme duty-cycling common in WSNs. To shorten the synchronization time, Transmitted-Reference (TR) [12] modulation is proposed, as shown in figure 1.…”

-Improving interference robustness in Ultra-Low Power (ULP) receivers is a big challenge due to their low power budget. This paper presents an envelope detector based 915MHz 10kbps ULP receiver, which is fabricated in 65nm CMOS process for Wireless Sensor Networks (WSN) and Internet of Things (IoT). Two power-efficient techniques:Transmitted-Reference and Shifted Limiter, are proposed to improve the interference robustness. The receiver sensitivity is between -61 and -76dBm. The maximum in-band Signal-to-Interference Ratio (SIR) at +/-1MHz offset is up to -50dB while just consuming 175µW power from a 1V supply.
