“…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

A fully-integrated reconfigurable dual-band transceiver (TRX) is presented for short range wireless communication. The TRX has two independent RF front-ends for each band with a shared analog baseband to achieve optimum power and cost. In Sub-GHz (760-960MHz) band, the maximum 75dBc 3 rd harmonic rejection ratio (HRR) is achieved by inserting a RFA with notch filtering. In 2.4GHz band, a single-ended-todifferential (S2D) RFA with phase and gain error compensation is proposed. By optimizing two bands separately, the RX achieves a NF of 5.1dB and 4.2dB, respectively. A -fractional-N PLL with two switchable Class-C VCOs is employed to provide the LOs. Moreover, the multi-mode CMOS PAs are integrated, which achieve the measured output P1dB (OP1dB) of 16.3dBm and 14.8dBm with 25% PAE for Sub-GHz and 2.4GHz bands. Furthermore, to optimize the PA's back-off efficiency, the powercontrol loop is proposed to detect the input signal PAPR in real time and flexibly reconfigure the PA's operation modes. With this proposed technique, the PAE in Sub-GHz band is improved by ×3.24 and ×1.41 at 9dB and 3dB back-off powers. In 2.4GHz band, the PAE is improved by ×2.17 at 6dB back-off power. The measured results have demonstrated that this presented transceiver has achieved comparable or even better performance in terms of noise, HRR, OP1dB and power efficiency compared with the-state-of-the-arts.I.
