Specifically, low-power receivers (RX) have been developed that efficiently receive data and extend the battery life for energy-constrained IoT systems. This has led to innovations in energy-detector (ED) first RXs which can achieve much lower power than traditional mixer-based heterodyne architectures. However, at such low-power levels, the RX performance is extremely limited. Oftentimes, low-power RXs have severe performance limitations, including lower data rate, limited blocker rejection, lower sensitivity, lower tolerance to PVT, limited modulation compatibility, and increased size and cost of off-chip components to achieve passive gain. This greatly limits the application of such RXs in real-world applications and prevents many of the low-power circuit techniques from translating to commercial standards. In this work, we look to motivate research into low-power heterodyne RX architectures which can support higher order modulation and have improved RX specifications while retaining low power.","PeriodicalId":100633,"journal":{"name":"IEEE Open Journal of the Solid-State Circuits Society","volume":"3 ","pages":"225-238"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10275080","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136208330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wearable magnetic field sensors offer a noncontact and portable method for sensing biopotentials. This article presents a readout circuit in 180-nm CMOS for strain-modulated multiferroic vector magnetic field sensors. By utilizing a demodulator-first architecture, the circuit bandwidth and dynamic range requirements are greatly reduced allowing for a low power consumption of 5.9 mW. The circuit bandwidth is from 76 mHz to 2.2 kHz, allowing for measurement across the range of interest for biomagnetic signals. Utilizing a modulation noise cancellation technique, the noise performance of the sensor system is significantly improved, and the sensor modulation amplitude can be increased, resulting in improved sensor sensitivity.

It enables a multiantenna WiFi mode with reconfigurable beam steering of single-sideband (SSB) quadrature phase shift-keying (QPSK) signals, while also facilitating omnidirectional SSB BLE-to-BLE backscatter communication. To achieve beam steering, two techniques are proposed: 1) a transmission-line-less fully reflective SP4T backscatter switch is employed to minimize power loss and maximize the communication range and 2) a multiantenna array is constructed using the aforementioned SP4T switches together with a baseband phase-shifting technique to reradiate the incident WiFi signal with a controllable angle of direction.

To achieve high-precision recognition of ten keywords under 5 dB~Clean wide range of background noises, a convolution neural network consists of four convolution layers and four fully connected layers, with modified sparsity-controllable truncated Gaussian approximation-based ternary-weight training is used. End-to-end optimization composed of three techniques is utilized: 1) the stage-by-stage bit-width selection algorithm to optimize the hardware overhead of FFT; 2) the lossy compressed TWN with symmetric kernel training (SKT) and dedicated internal data reuse computation flow; and 3) the error intercompensation approximate addition tree to reduce the computation overhead with marginal accuracy loss.

The AM–PM distortion behavior of the current-mode/voltage-mode power amplifiers (PAs) is detailed and an AM–PM compensation technique for both modes is introduced. The proposed design utilizes one current-mode DPA as the main path PA and a class-G PA voltage-mode digital PA as the auxiliary path PA, combined through a single-transformer footprint. It provides enhanced linearity through built-in adaptive biasing and hybrid current-/voltage-mode Doherty-based power combining. As a proof of concept, a 1.2–2.4-GHz wideband DPA is implemented in the Globalfoundries 45-nm CMOS SOI process. The measurements show a 37.6% peak drain efficiency (DE) at 1.4 GHz, and 21.8-dBm saturated output power (Psat) and \u0000<inline-formula> <tex-math>$1.2times /1.4times $ </tex-math></inline-formula>\u0000 power back-off (PBO) efficiency enhancement, compared to the ideal class-B at 3 dB/6 dB PBO at 1.2 GHz.

Traditional disease treatment is shifting toward preemptive, personalized healthcare. For these biomedical electronics to work seamlessly, careful design of integrated circuits for sensing, signal processing, and powering is crucial. However, biomedical applications often are under unique and harsh environments, such as under extremely stringent power budgets and fluctuating supply voltages; on top of this, such applications require hermetic sealing with robust communications. Moreover, we also need to consider various aspects that other applications do not normally consider. As an example, the human body absorbs GHz range electromagnetic signals significantly, making typical RF communication and powering technologies such as Bluetooth or wireless power transfer (WPT) in GHz not an ideal choice in/around body area [1]. Also, with the rise of artificial intelligence and machine learning, personalized healthcare is becoming more popular, but for some applications, “personalized” means that training sets may get scarce, posing issues to achieving high sensitivity and specificity at once. This special Section will present the latest developments in integrated circuits in biomedical electronics to overcome the aforementioned issues: powering, sensing, and processing.","PeriodicalId":100633,"journal":{"name":"IEEE Open Journal of the Solid-State Circuits Society","volume":"3 ","pages":"63-64"},"PeriodicalIF":0.0,"publicationDate":"2023-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/8782712/10019316/10174830.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67861769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
