This letter presents a low‐noise and high‐gain CMOS mixer that uses a simple dynamic current‐bleeding (DCB) technique. The conventional static current‐bleeding (SCB) technique has high conversion gain and low noise figure at a high intermediate frequency (IF) but also has moderately high direct‐mechanism flicker noise. Meanwhile, the conventional DCB technique possesses completely opposite characteristics. The proposed DCB technique obtains not only low direct flicker noise and low noise figure at high IF, but also has high conversion gain by combining only the advantageous features of both conventional techniques. Measurement results show a conversion gain of 21.2 dB and a noise figure of 16.3 dB at 10 kHz and 5.6 dB at 10 MHz, while the mixer consumes 4.2 mW at a 1.2 V supply voltage. It was implemented in a 0.11‐μm CMOS process with a chip area of 0.8 × 0.8 mm2. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:1267–1271, 2017

“…Dynamic current injection technique with a shunt tuning inductor has been designed in order to reduce the effect of tail capacitance at the node between the local oscillator (LO) switches and RF transconductance stage for 2.4GHz applications [5,6]. Also, in our previous study, differential active inductor is employed instead of the tuning spiral inductor in the Gilbert cell mixer for 5GHz application [7].…”

This paper presents the design and measurement of low flicker-noise, high conversion gain double-balanced Gilbert cell mixer in CMOS process. Since the noise figure (NF) of the CMOS mixer is strongly affected by flicker noise (1/f noise), a dynamic current injection technique is used to reduce the flicker noise corner frequency. An inductor is employed to tune the tail capacitance in the local oscillator and the RF transconductance stages. So, it reduces the RF leakage through this parasitic capacitance. Moreover, output band elimination filter (BEF) is employed to suppress the leakage of the RF signal. The mixer is designed using TSMC 0.18 μm CMOS process. Simulations and measurements had been performed. The proposed mixer has a simulated conversion gain of 15dB and single side band noise figure is 10.6dB at 20kHz. Index Terms -CMOS mixer, Gilbert cell mixer, flicker-noise, band elimination filter.

In this article, a novel 1.8-5 GHz downconversion mixer is presented. The mixer is designed and simulated using SiGe 8HP 130 nm CMOS process technology. The proposed mixer is implemented by incorporating a double-balanced configuration, active inductor, and current mirror techniques. For performance optimization of the proposed mixer, different algorithms such as the genetic algorithm (GA), inclined plane system optimization (IPO) algorithm, and particle swarm optimization (PSO) algorithm have been used. Compared to existing works, this design shows an enhanced conversion gain (CG), a third-order input intercept point (IIP3), and return loss ( S 11 ) at the expense of the noise figure (NF). Additionally, the design consumes low power and covers a small chip area compared to other state-of-the-art devices. PSO shows the most promising results when compared to other optimization algorithms’ results. According to the measurement results after PSO optimization, the mixer attains a maximum CG of 25 dB, an IIP3 of 4 dBm, and a NF of 5.2 dB at 5 GHz, while consuming only 15 mW of DC power. The mixer operates at 1.2 V and covers 0.8 mm2 die area.
