“…There are many active and passive circuits that have been designed to change an unbalanced signal into a differential one [21,22]. There are simple circuits, such as a singletransistor (Figure 2a) [24] or differential circuits (Figure 2b) [5,20], and more complex ones, such as common-gate-common-source baluns (Figure 2c) [1][2][3][4]6,13,16,17,19,[21][22][23].…”

A new 1.575 GHz active balun with a classic double-balanced Gilbert mixer for global navigation satellite systems is proposed herein. A simple, low-noise amplifier architecture is used with a center-tapped inductor to generate a differential signal equal in amplitude and shifted in phase by 180°. The main advantage of the proposed circuit is that the phase shift between the outputs is always equal to 180°, with an accuracy of ±5°, and the gain difference between the balun outputs does not change by more than 1.5 dB. This phase shift and gain difference between the outputs are also preserved for all process corners, as well as temperature and voltage supply variations. In the balun design, a band calibration system based on a switchable capacitor bank is proposed. The balun and mixer were designed with a 110 nm CMOS process, consuming only a 2.24 mA current from a 1.5 V supply. The measured noise figure and conversion gain of the balun and mixer were, respectively, NF = 7.7 dB and GC = 25.8 dB in the band of interest.

“…Solutions based on one transistor can also be found in the literature [24], as well as various solutions using a differential amplifier circuit as a balun circuit [5,20]. In integrated circuits, passive baluns for low frequencies have very large dimensions.…”

“…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 .
