“…The measured third-order intercept point of the mixer is plotted in Figure 6, which features a measured IIP3 of À5.5 dBm. Figure 7(a) shows the measured NF for the proposed mixer with DAI and it found to be 15 dB at 10 MHz, with 300 KHz flicker noise corner frequency, as shown in Figure 7(b), which is extremely lower than 1.5 MHz corner frequency obtained in [7] even by using bulky passive inductor as tuning inductor. Table 1 shows a comparison between the proposed mixer with Ref.…”

“…It shows that the proposed mixer using dynamic current injection and DAI has a good performance, specially, with a comparable conversion gain and lower flicker noise corner. The proposed mixer has $10% increase in chip size as the DAI has been added, whereas the mixer in [7] has about 53% larger chip area due to the additional tuning spiral inductor.…”

“…V inj is used to control the height of the injected current pulses. A parallel tuning inductor have been used to tune out the parasitic tail capacitances (C p ) [7], as shown in Figure 1, also, series inductor can used as in [2]. In the proposed design, the spiral inductor has been replaced by a DAI, which consumes small chip area and has many other advantages over spiral one, as will discussed in the next section.…”

“…Many designs have been proposed to reduce the output flicker noise of the mixer. Static current injection has been proposed in [5], dynamic current injection proposed in [6], and the same design in [6] has been used by Yoon et al [7], with a shunt tuning inductor has been added to reduce the effect of tail capacitance (Cp) at the node between the local oscillator (LO) switches and RF transconductance stage. This design in [7] gives a good results but it sacrifices the chip size by using a bulky spiral inductor.…”

This article presents a low flicker noise (1/f), doublebalanced Gilbert-cell mixer. As the down converted base-band signal is strongly affected by the low-frequency flicker noise, resulting in mixer signal-noise ratio (SNR) degradation, a dynamic current injection technique has been used to reduce the flicker noise corner frequency. Differential active inductor has been used to tune the tail capacitance at the node between the local oscillator (LO) switches and the radio frequency (RF) transconductance stages, resulting in reduction of RF leakage. RF and LO leakage has been minimized by adding an on-chip low-pass filter to the mixer output. The mixer has been designed and fabricated using Taiwan Semiconductor Manufacture Company (TSMC) 0.18-lm 1P6M complementary metal-oxide-semiconductor FET (CMOS) process. The performance of the fully integrated mixer is given. With RF of 2.4 GHz, intermediate frequency of 10 MHz and LO power of À5 dBm, conversion gain of 12 dB, input third order intercept point (IIP3) of À5.5 dBm, and single-side band noise (SSB-NF) figure of 15 dB with flicker noise corner frequency of 300 KHz had been measured. The mixer consumes 19.8 mW from 1.8 V supply.

The implementation of software-defined radio necessitates a versatile radio frequency (RF) front-end that can support multiple standards in different frequency bands. This article presents the state-of-the-art multiband and wideband mixers in the context of different receiver architectures suitable for softwaredefined radio (SDR). Wideband and multiband mixer designs reported in the literature are categorized on the basis of their circuit architecture. This study tabulates the results of mixer designs with an emphasis on noise figure (NF), conversion gain (CG), linearity, and image rejection ratio. The best parameters reported in the comparison are 68-84 dB of CG, 3.2 dB of NF, 2.5 mW of power consumption, 12.5 dBm of third-order input intercept point, and 0.015 mm 2 of area at different frequencies. The study also discusses the design challenges and techniques to overcome those issues. The article concludes with the summary and prospective developments for SDR architectures.

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.
