This paper presents an F-band power amplifier (PA) designed using novel back-end-of-line (BEOL) in Intel 16 technology. In the PA transistor array, skip-layer vias which directly connect transistor to thick metal layers are used to reduce parasitics from BEOL and improve the PA performance. This 2-stage PA shows excellent peak PAE and gain per stage. At 110GHz, the measured $mathrm{P}_{text{sat}}$, peak PAE, linear power gain, and OP1dB are 11.8dBm, 23.8%, 17.1dB, and 9.2dBm, respectively. The core area of the PA is 0.023mm2, enabling compact integration into phased array or waveguide based transceivers. To the authors' knowledge, this is the first circuit demonstration using skip-layer via that operates beyond 100GHz.

A low-phase-noise mm-W low-power quadrature differentially injection-locked digitally-controlled oscillator (QILDCO) is presented. This work adopts a differential injection to enable a trade-off between phase noise performance and power consumption. Switched-capacitor banks and active devices are integrated inside the inductor loop to reduce the active area. The total active area is 0.109 mm2 including harmonic extractors and buffers (excluding I/O pads). The proposed oscillator is supporting two 5G mm-W bands below 30 GHz with a tuning range of 21.3%. The prototype has been implemented in 65-nm Partially-Depleted SOI (PD-SOI) CMOS process. It achieves best state-of-the-art jitter of 25.6 fs while consuming 22 mW from a 1 V supply voltage.

This article presents two Ka-band low-noise amplifiers (LNA) for millimeter-wave (mm-wave) phased-arrays. The folded three-coil transformer and EM dual-feedforward techniques are proposed to improve the LNA's noise performance and reduce the chip area. The first two-stage single-ended LNA, consisting of a common-gate (CG) input stage and a common-source (CS) output stage, achieves 1.9 dB minimum noise figure (NF), 16.7 dB peak gain, 4.3 GHz 3-dB bandwidth (BW) from 25.6 to 29.9 GHz, and -12 dBm input 1-dB gain-compression-point (IP1dB) with 13.2 mW Pdc. The second LNA employs the current-reuse topology, which reduces the power consumption to 3.6 mW at the cost of a 0.6 dB NF degradation. The proposed LNAs have been fabricated in 65nm CMOS process. The two LNAs have the same 200 µm × 300 µm core chip area.

This work presents a novel switch-less reconfigurable triple-/push-push dual-band VCO topology and design methods for a W-band metal-oxide-semiconductor (CMOS) voltage-controlled oscillator (VCO). A clover-shaped inductor with a three-port connection and single frequency multiplied output port configuration provides switch-less mode changes between triple-push and push-push operation. This topology is demonstrated in a W-band VCO by controlling three cores with a measured phase noise of −109.17 dBc/Hz at a 10-MHz offset of a 105.3 GHz carrier. The measured center frequency of each band is 91.04 GHz and 102.33 GHz with a tuning range of 10.4% and 14.1 %, respectively. The proposed VCO with independent core on/off state control enables low parasitic switch-less frequency band shift resulting in a superior tuning range compared to those of conventional dual-/single-band VCOs. The effectiveness of this approach is demonstrated through fabrication in a 28-nm CMOS process, with the best FOMT being −174.4 dBc/Hz in this case.

This paper presents a novel capacitor assisting triple-winding transformer (CTTF) low noise amplifier (LNA) with ultra-low noise figure (NF) and a flat passband gain in 130nm SOI CMOS process. The assisting capacitor in the triple-winding transformer expands the design space by enabling independent control of the coupling strength between each two inductors. The negative resistor enhanced by the assisting capacitor boosts the transformer gain that not only suppresses the noise from the second stage, but also leads to a wider passband by compensating the gain droop from the active transistors. Through two-stage simultaneous noise and power matching, the LNA provides a remarkable 0.8-1.5 dB NF, <−14dB S11, <−8dB S22, −11.8dBm IP1dB and 21.8-23.3dB power gain across the 6-12GHz passband with ±0.75dB ripple while drawing 20mA from a 3.3V supply. It reports the lowest NF so far.

We present a Cartesian I/Q modulator based on dual 10-bit RF-DACs. Non-overlapping LO signals and a segmented RF - DAC architecture with scaled bit currents contribute to good linearity and allow low-complexity DPD. Unit-cell flip-flops with a balanced clock distribution enable a high sample rate. Drive slope control for data switches reduce out-of-band emissions. Implemented in 22 nm FDSOI CMOS, the modulator operates up to 26 GHz with a maximum sample rate of 11 GS/s. The modulator is used to demonstrate transmission of a 64QAM signal at 13.2 Gb/s, a 256QAM signal at 7.33 Gb/s, and an OFDM signal comprising four aggregated 400-MHz 64QAM channels at an EVM of 6.43 %. The results demonstrate the potential of the proposed modulator architecture for realization of ultra wideband transmitters for high performance mm-wave systems.

A 915MHz ultra-low-power blocker-enhanced wake- up receiver (BE-WuRx) is presented in a 65nm CMOS process. Employing the proposed frequency-hopping two-tone modulation (FH-TTM), the BE-WuRx can dynamically convert the in-band blocker power to data power, and achieves a −63.6dBm sensitivity without blocker and a −90dBm enhanced sensitivity with a −25dBm CW interferer, while just consuming $mathbf{19}mathbf{mu}mathbf{W}$. With the −63.6dBm sensitivity, the BE-WuRx performs 53dB tolerance to the in-band blocker, exhibiting 14dB improvement compared to the case that FH- TTM is off. The wake-up latency is 6.4ms for a quiet channel and 6.4 to 64ms for a congested channel.

This paper presents an energy-efficient wideband D- band wireless link using receiver (RX) and transmitter (TX) modules based on a channel-bonding scheme. The modules include RX and TX integrated circuits (ICs) fabricated in 45nm CMOS RFSOI technology. They are mounted on low-cost multi-layer printed circuit boards (PCBs) and connected to patch antennas. The RX and TX ICs are composed of two down-conversion and up-conversion chains, respectively, operating over contiguous sub- bands around 147.96 GHz. The required multiple millimeter-wave local oscillator signals (LOs)are generated on-chip. The presented wireless system achieves a data rate of 56.32 Gb/s by using 16 QAM modulation over 8 radiofrequency (RF) channels, with a competitive energy consumption (RX+TX) of 18 pJ/bit, including the LOs generation circuitry.

This paper presents a dual-loop chip-scale molecular clock (CSMC), which enhances the Allan Deviation performance by combining high signal-to-noise ratio of using fundamental mode and long-term stability of using higher order modes in derivative molecular absorption spectroscopy. In addition, digital frequency-error integration is adopted in the frequency-locked loop to provide an infinite open-loop DC gain, which fully suppresses any frequency drift caused by the temperature-sensitive crystal oscillator. This new generation CSMC is implemented in 65-nm CMOS, and achieves 20 ppt (part-per-trillion) Allan Deviation at 10,000 s averaging time with 71-mW power consumption.

In addition, digital frequency-error integration is adopted in the frequency-locked loop to provide an infinite open-loop DC gain, which fully suppresses any frequency drift caused by the temperature-sensitive crystal oscillator. This new generation CSMC is implemented in 65-nm CMOS, and achieves 20 ppt (part-per-trillion) Allan Deviation at 10,000 s averaging time with 71-mW power consumption.","PeriodicalId":415294,"journal":{"name":"2022 IEEE Radio Frequency Integrated Circuits Symposium (RFIC)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125298394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
