“…Although the small signal transfer function of this filter topology is similar to the mixer presented in [7], their linearity and large signal behavior is very different. This is because the mixer switches are driven by a transconductance stage in [7], which is the key bottleneck in achievable linearity.…”

“…1, acting as a downconversion mixer with a high-pass baseband response. Due to the X-coupling with the wideband switch-R mixer, the combined conversion gain to baseband becomes low-pass; 1 -s /(1+s ) = 1/(1+s ), similar to the transconductance-switch-C circuit in [7]. The switch-RC path can also be seen as an N-Path notch filter [2], resulting in band-pass RF filtering when subtracted from a unity transfer.…”

-With the growing amount of wireless devices, interference robustness is a receiver specification of increasing importance. This paper presents a technique that improves both out-of-band compression and weakly non-linear distortion. It mitigates the effect of non-linearity in the baseband amplifier by preceding it by a cross-coupled passive filter. This provides a highly linear passive shunt path for out-of-band currents, while maintaining wideband input matching. The 65nm CMOS prototype chip achieves 41dBm out-of-band IIP3 at 40MHz offset and an 11dBm out-of-band blocker compression point. The chip has an area of 0.8mm 2 and consumes 46mW from a 1.2V supply. Index Terms -Mixer-first receiver, passive mixer, high linearity, blocker tolerance.

“…Mixer is one of the most important analog blocks in the wireless communication system. Typically, the Gilbert active mixers [1][2][3][4][5][6][7][8][9][10] are widely used in the wireless communication systems for their superior conversion gain and port to port isolation. However, conventional Gilbert active mixers generally consume a significant portion of the power of the transceiver, and the LV-LP mixers have received considerable attentions in recent years.…”

Summary This letter describes a low‐voltage low‐power (LV‐LP) 2.4‐GHz mixer for Industrial, Scientific and Medical (ISM) band wireless applications. The approach is based on a two‐stage amplifier, and the Gilbert switch stage is inserted between the two amplifier stages. The proposed amplifier‐based mixer delivers a remarkable conversion gain of 13 dB with a local oscillator (LO) power of 7 dBm, while consuming only 1.05‐mW DC power from a 0.8‐V supply voltage. The input‐referred third‐order intercept point (IIP3) of the mixer is 3.82 dBm, and the chip area is only 0.429 mm2. The results indicate that this mixer is suitable for the low‐voltage low‐power applications. Copyright © 2014 John Wiley & Sons, Ltd.

This paper describes a low voltage low power (LV-LP) folded mixer for S-band wireless applications. The proposed mixer could convert a 10 MHz intermediate frequency (IF) signal to a 2.4 GHz RF signal with a local oscillator (LO) power of 0 dBm at 2.39 GHz. The comparison with the previous reported mixers shows that the proposed mixer has the advantages of lower voltage, lower power consumption and higher conversion gain than most of the other works. Simulation results demonstrate that the mixer a remarkable conversion gain of 10.5 dB while consuming only 0.65 mW DC power from a 0.8 V supply voltage. The input-referred third-order intercept point (IIP3) of the mixer is 3.75 dBm, and the chip area is only 0.525 mm 2 .
