This paper presents a fractional-N PLL frequency synthesizer with self-calibration digital loop engines for fast frequency acquisition and noise-driven optimization of loop filter bandwidth, VCO frequency and amplitude control. The PLL is implemented in a 28nm FDSOI CMOS technology and its noise performance is optimized by employing a dual-edge PFD architecture, charge pump linearization, and bias sampling and a spur-less, single-stage multiple feedback sigma delta modulator to achieve a typical rms jitter of 175 fs, while drawing 21 mA from a 1.8-V supply.

The generation of the carrier signal with a very low spur level is a key challenge in all the communication systems, especially those operating at mm-waves, where a frequency multiplier is typically used to break the tradeoff between high frequency of operation and low phase noise. This letter describes a frequency tripler tailored to cover the fifth generation new radio 39-GHz frequency range. By embracing the edge-combining concept, together with the combination of a single-stage polyphase filter and a multipoint injection-locked ring oscillator, the proposed frequency multiplier is able to offer robust and consistent high harmonic rejection ratio over a large fractional bandwidth. Fabricated in 28-nm bulk CMOS technology, the measured frequency multiplier features >40-dBc harmonic rejection over an outstanding 35% fractional bandwidth, while consuming 25 mW only from 0.9-V supply. To the best of our knowledge, the proposed multiplier achieves the highest harmonic rejection among the state-of-the-art multipliers in CMOS and BiCMOS technologies, while having 60% smaller area.

This paper presents the design and the experimental validation of a 6th-order continuous-time low-pass filter in 28 nm bulk-CMOS, based on the cascade of 3 Rauch biquadratic cells. Each cell exploits a broad-bandwidth Operational Transconductance Amplifier (OTA), without Miller compensation scheme for differential Loop Gain stability. This maximizes the OTA unity gain bandwidth, with no power increase w.r.t classical compensation schemes, and improves both frequency response accuracy and linearity over the filter pass-band. This aggressive design choice is sustained by the higher 28 nm CMOS transistor’s transition frequency and by the intrinsic feature of the Rauch cell, whose R-C feedback/direct path nets introduce two poles and two zeros that self-compensate the differential loop-gain. On the other hand, the proposed OTA only exploits a compensation scheme for the common-mode signal stability, which does not affect the differential signal. The prototype synthesizes 50 MHz low-pass frequency response at 3.3 mA current consumption from a single 1.1 V supply and performs 18 dBm and 16.5 dBm Input IP3 for 10&11 MHz and 40&41 MHz input tones, equalizing the linearity performance over the filter pass-band, just thanks to the OTA wider bandwidth. This finally allows 153 dBJ-1 and 158 dBJ-1 Figure-of-Merit at 10&11 MHz and 40&41 MHz input tones.

This letter describes a compact resistor-based temperature sensor intended for the thermal monitoring of microprocessors and DRAMs. It consists of an RC poly phase filter (PPF) that is read out by a frequency-locked loop (FLL) based on a dual zero-crossing (ZC) detection scheme. The sensor, fabricated in 65-nm CMOS, occupies 5800 μm2 and achieves moderate accuracy [±1.2 °C (3σ)] over a wide temperature range (−50 °C to 105 °C) after a one-point trim. This is 2× better than the previous compact resistor-based sensors. Operating from 0.85 to 1.3-V supplies, it consumes 32.5-μA and achieves 2.8-mK resolution in a 1-ms conversion time, which corresponds to a resolution FoM of 0.26 pJ•K2.

A low-power quadrature local oscillator (LO) generation scheme embedded in a direct-conversion E-band transmitter (TX) is presented. A single-stage polyphase filter is closed in a loop and continuously tuned by means of a quadrature phase detector to maintain precise I/Q signals independently from LO frequency and component variations, thus making the solution wideband and robust against process, supply, and temperature variations. The analog phase detector, realized with fully balanced analog multipliers, is critical to reach high accuracy. Careful circuit analysis and simple design solutions are proposed to avoid systematic phase errors and to maintain high detector gain despite the high operating frequency. The TX, realized in BiCMOS 55-nm technology, delivers a maximum linear output power of 20.5 dBm at 80 GHz with 14% power efficiency. The LO buffers consumes 115 mW from 2.3-V supply while the LO calibration circuits need 16 mW only and allows to maintain a remarkable image rejection ratio of 40 dB or better over 70–90 GHz.

This paper presents a fully-integrated optical receiver in 28nm bulk CMOS for 1310 and 1550nm light, suitable for single-mode fiber communication. The fill factor of the Schottky photodiodes is maximized and the transimpedance amplifier is based of a voltage amplifier with high gain. This technique reduces the input-referred noise current for a given bandwidth. The receiver has a core area of 145x185µm2, while consuming 42mW. The circuit achieves data rates up to 3Gb/s at a BER of 3e-8 and a sensitivity of 0.1dBm for 1310nm light, and up to 1Gb/s at a BER of 4.8e-9 and sensitivity of 0.5dBm for 1550nm light.

A digital polar transmitter is presented that uses a digital-to-time-converter (DTC) to enable high-efficiency polar RFDAC for multiband and wide-channel applications. The transmitter uses coarse division inherent in DTC operation to generate TX output frequencies from 0.7 to 2.2 GHz with DCO tuning range of only 7.3–8.7 GHz (±8.7%). The TX was fabricated in 14-nm FinFET and achieves noise of −153/−150 dBc/Hz for LTE5/LTE20 in Band1 with DTC power dissipation of 27 mW. The DTC was implemented using digital Automatic-Place-and-Route tools, requiring very limited analog layout resources.

Quantum computers hold the promise to solve some of the most complex problems of today. The core of a quantum computer is a quantum processor, which is composed of quantum bits (qubits). Qubits are fragile and their state needs to be corrected in real time by a classical controller. Today, the control of qubits is done at room temperature by racks of instruments, while qubits operate at several tens of milli-Kelvin. To ensure compactness, and eventually scalability, we have proposed the use of controllers operating at a few Kelvin, so as to reduce the length of control cables, while potentially enabling superconductive interconnects, which enable virtually zero resistance and low thermal conductivity. We have chosen CMOS to achieve this functionality due to its scalable nature and overall miniaturization opportunities. Cryogenic CMOS, or cryo-CMOS, circuits and systems need to be carefully designed, so as to ensure low noise and high bandwidth, while operating at strict power budgets of a few milliwatts per qubit. In this paper, we outline the requirements of a classical controller and we show examples of such circuits and systems. Results and perspectives are presented discussing a roadmap for the future.

The 3.14mm x 2.47mm testchip is fabricated in 9-metal 65nm bulk CMOS, contains the secure 10x10 tile FPGA fabric (six 6-input LUTs each), and runs at 290MHz at nominal 1V VDD and room temperature. The 38,400 PUF bits exhibit high uniqueness, randomness, and a BER < 8.1*10−12.","PeriodicalId":402948,"journal":{"name":"ESSCIRC 2019 - IEEE 45th European Solid State Circuits Conference (ESSCIRC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125315871","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}
