“…1(a) shows the schematic of the proposed CMOS mixer based on a modified Gilbert mixer topology, where the tail current source and the RF transconductance stage in a conversional Gilbert mixer are replaced by a Marchandbalun-based RF stage to reduce the supply voltage [10]. In addition, an active load that is composed of two PMOS transistors (M 9 and M 10 ) and two common-mode feedback resistors (R 1 and R 2 ) is employed to provide a high load impedance [11].…”

“…Compared with a commonly used lumped poly-phase filter [12], [13], the passive four-way quadrature divider has a much lower insertion loss in the mmW range at the cost of a larger chip size. In addition, the transimpedance amplifier (TIA), which is composed of an NMOS transistor M bn , a PMOS transistor M bp and a feedback resistor R F (500 ), is utilized as an intermediate-frequency (IF) output buffer [11].…”

“…The proposed CMOS mixer can be switched as either a SHM or a fundamental mixer (FM) for dual-band applications. By using a modified Gilbert mixer topology [10] and an active load [11], the proposed CMOS mixer can operate at 1 V supply voltage and −3 dBm LO pumping power while maintaining a good performance in both SHM and FM modes. The 1V supply voltage and −3 dBm LO power make it suitable for low-voltage and low-power applications.…”

In this paper, we propose, investigate, and demonstrate a reconfigurable low-voltage and low-power millimeter-wave mixer in a 65-nm CMOS, which can be switched as either a subharmonic mixer (SHM) or a fundamental mixer (FM) for the dual-band applications. Based on a modified Gilbert mixer topology, the proposed CMOS mixer can operate at a low supply voltage and low local oscillator (LO) pumping power while providing good performance in both SHM and FM modes. To the best of our knowledge, this is the first reported Gilbert SHM based on the stacked switching quads in a low-voltage CMOS technology. Under 1-V supply voltage and −3-dBm LO pumping power, the measured conversion gain (CG) of the proposed CMOS mixer is −4.8 ± 1.5 dB from 34 to 56 GHz and −0.1 ± 1.5 dB from 17 to 43 GHz in the SHM and FM modes, respectively. The measured double-sideband (DSB) noise figure (NF) is 18.5-20 dB from 37 to 49 GHz and 12.4-14 dB from 17 to 35 GHz in the SHM and FM modes, respectively. The measured input third-order intercept point (IIP3) is 2.9 and 3.4 dBm, respectively, for the SHM and FM modes at the LO frequency of 22 GHz. In addition, the total dc power consumption of the proposed mixer including output buffers is 7 mW in both the operation modes.INDEX TERMS CMOS, dual-band mixer, fundamental mixer (FM), Gilbert mixer, low-power, low-voltage, millimeter-wave (mmW), reconfigurable, subharmonic mixer (SHM).

“…Introduction: A down-conversion mixer which converts the RF signals to the IF signals is an essential component of the wireless communication systems [1][2][3][4][5][6][7][8][9]. The Gilbert-cell mixer with the advantages of good conversion gain (CG) and superior spur rejection in a compact size is widely used in modern CMOS transceiver integration circuits [1][2][3][4].…”

“…Nevertheless, the large LO power requirement increases the dc power burden of the LO part, especially at high frequencies. To solve this problem, the weak-inversion technique is adopted in this work [8,9]. The weak-inversion biasing technique which gate-source voltage (V GS ) is lower than the threshold voltage provides a superior performance on the ratio of transconductance (g m ) to dc current than the strong inversion bias.…”

An ultra-low-LO (local oscillator)-power X-band down-conversion ring mixer in 0.18-μm CMOS process is presented. By using the weak-inversion biasing technique, the proposed X-band ring mixer exhibits low-dc-power consumption and low-LO-drive power while maintaining a reasonable conversion gain (CG). The measurement results show that the proposed mixer demonstrates a maximum CG of 1.75 dB with ultra-low-LO-power of −8 dBm at RF of 12 GHz and IF of 100 MHz. The dc power is only 2 mW. The 3-dB RF bandwidth is from 9 to 15 GHz and the output 1-dB compression point (OP 1 dB) is −14 dBm.

A mixer is an indispensable device in the RF transceiver system. Along with the rapid development of mobile communication technology, the demand on the RF mixer for compatibility with multiple communication standards and functional diversity is increasing. As a result, the mixer with wider bandwidth, lower noise, higher linearity, and less power consumption is urgently needed.In the article, the basic principle and the circuit architectures of the mixer are reviewed, including the essential performances such as linearity, noise, gain, bandwidth, and so forth. In addition, several aspects are presented, compared, and discussed with particular emphasis on optimization design approach and performance. Current design and fabrication challenges, future development, application areas of the mixer and visions for the mixer are also discussed in this review.
