High-sensitivity super-regenerative receivers (SRXs) are demonstrated at 96 and 135 GHz, respectively, in this paper. They are based on highquench-controlled metamaterial resonators with a differential transmission line loaded with a split-ring resonator (DTL-SRR) and a differential transmission line loaded with a complementary split-ring resonator (DTL-CSRR) in 65-nm CMOS. Highoscillatory amplifications are established by the sharp stopband introduced by metamaterial resonators. As such, high detection sensitivity is achieved for SRXs at millimeter-wave regions. The fabricated 96-GHz DTL-CSRR-based SRX has a compact core chip area of 0.014 mm with measured power consumption of 2.8 mW, sensitivity of 79 dBm, noise figure (NF) of 8.5 dB, and noise equivalent power (NEP) of 0.67 fW Hz. The fabricated 135-GHz DTL-SRR-based SRX has a compact core chip area of 0.0085 mm with measured power consumption of 6.2 mW, sensitivity of 76.8 dBm, NF of 9.7 dB, and NEP of 0.9 fW Hz. Compared to the conventional SRX with an LC-tank-based resonator at similar frequencies, the proposed SRXs have 2.8 4 dB sensitivity improvement and 60% smaller area. The integrated SRXs are also demonstrated for the imaging applications.Index Terms-Imaging, metamaterial resonator, 65-nm CMOS, super-regenerative receiver (SRX).

“…The growing demand for higher-rate wireless data transfer (e.g., gigabit wireless Ethernet) has resulted in a plethora of research activities in transceiver design for mm-wave bands where relatively less populated spectrum with larger bandwidths are available [1][2][3][4][5][6][7][8]. For example, the available 7-GHz spectrum in the unlicensed 60-GHz band, provides sufficient bandwidth for high-data-rate applications such as gigabit wireless Ethernet, video distribution through mobile devices and content exchanging of compressed/ uncompressed streaming data [2].…”

In this paper, a low-phase-noise 67-GHz CMOS oscillator is presented. This inductorless voltagecontrolled oscillator (VCO) employs a combination of standing-wave and travelling-wave oscillators to generate multi-phase outputs. A filtering technique is used to reduce the phase noise of the VCO. The oscillator achieves a tuning range of 5.2 GHz using a combination of coarse and fine tuning methods. The proposed multi-phase oscillator is designed and fabricated in a 0.13-lm CMOS process. Operating at 67 GHz, the VCO consumes 14 mW from a 1.2-V supply and achieves an output phase noise of -95.66 dBc/Hz (-107.89 dBc/Hz) at a 1 MHz (10 MHz) offset. The chip area is 0.9 mm 2 . As an application example for the presented multi-phase oscillator, a polar transmitter structure is proposed. The transmitter is designed for systems that use a circular quadrature-amplitude modulation (QAM) constellation. A specific example of a 16-QAM transmitter is presented. The desired output phase is chosen by an 8-to-1 multiplexer, and a variable gain amplifier (VGA) is used to achieve the desired amplitude. Based on post-layout simulations, the 60-GHz 16-QAM transmitter consumes 43.2 mW from a 1.2-V supply.

this paper presents a low supply voltage, fundamental-frequency 90nm CMOS mm-wave oscillator using an enhanced LC tank with inductive division to improve the oscillator performance. The oscillator achieves a tuning range from 53.2GHz to 58.4GHz while consuming 8.1mW from a 0.7V supply. The phase noise at 58.4GHz is -90.08dBc/Hz @ 1MHz offset. The oscillator can also be operated from a supply voltage as low as 0.43V with a phase noise of -90.10dBc/Hz @ 1MHz offset from a 61.7GHz carrier, while consuming only 1.2mW.
