“…In the next phase of the study, it has been attempted to bias the gates of the mixer core which has been done for the first time, in this study. This has been done for similar mixers but without single‐to‐differential converter baluns and nonintegrated baluns . Figure shows the complete mixer circuit with single‐to‐differential baluns and biased gates.…”

A biased gates passive resistive ring mixer with integrated baluns in 0.18-lm CMOS Taiwan Semiconductor Manufacture Company (TSMC) process is reported. The mixer shows 10% improvement compared with the mixer without biased gates. This is the first circuit report of biased gates resistive ring mixer with integrated baluns. The circuit has been designed and optimized for 2.4 GHz RF frequency and for applying in the contactless heart rate extraction system using microwave Doppler radar. The circuit has the conversion loss of 8.36 dB for 2.4 GHz frequency and indicates 17% improvement compared to the similar types without gate biasing have been reported so far.

“…A double‐balanced resistive mixer also exhibits inherent high linearity [2, 3], and it has been shown to be suitable for both homodyne and heterodyne wireless transceivers [4]. Most double‐balanced mixers reported to date have been implemented using four MOSFETs (mixer core) and additional passive elements for RF [5–7], LO [5, 6], and IF matching [7], and to improve LO efficiency [8]. These passive elements occupy significantly more space on the chip die than the mixer transistor core.…”

“…These passive elements occupy significantly more space on the chip die than the mixer transistor core. In addition, typically, a double‐balanced mixer configuration requires single‐ended to differential transitions at the RF and LO ports, which are usually implemented off‐chip [4–9], adding cost, size, and complexity. If used in direct down‐conversion receivers, these mixers typically require DC cancellation circuitry to eliminate large DC offset [10, 11].…”

A 0.18‐μm CMOS wideband passive mixer fully integrated with baluns in IBM7HP process is reported. The mixer exhibits wideband operation, despite the intrinsic narrow‐band magnitude balance of passive baluns. Very low DC offset, of less than 3 mV, is achieved without any DC cancellation circuits, due to high LO–RF isolation. At the RF frequency of 2.4 GHz, the combined IF differential outputs provide conversion loss (CL) of 7.5 dB, input 1 dB compression point (IP1dB) of 6.2 dBm, and input third‐order intercept point (IIP3) of 15.5 dBm. This mixer exhibits broad‐band RF impedance matching with reflection coefficient magnitude better than −9.6 dB through the RF frequency range from 1 to 12 GHz. The CL of 10.1–12.9 dB, IP1dB of 8.6–14.4 dBm, and IIP3 of 16–22.2 dBm are achieved at this frequency range for broad‐band applications. © 2012 Wiley Periodicals, Inc.
