The conventional von Neumann architecture, in which large quantities of data are transmitted between processing units and memory units, creates a bottleneck in AI applications. In-memory computing (IMC) offers an efficient solution to this problem by enabling computations within memory units, thus reducing the need for data transmission. This paper proposes a multilogic sense amplifier (MSA) with a dynamic reference voltage (DRV) generation circuit (hereafter denoted as MSA-DRV) to enhance the performance and reduce the power consumption of static random-access memory (SRAM)-based IMC. The proposed MSA-DRV performs six logic operations, namely the AND, NAND, OR, NOR, XOR, and XNOR operations, within an SRAM array by using a novel DRV circuit. The DRV circuit enables the voltage threshold to be adaptively changed according to the requirements of different operations. Experimental results indicated that the proposed MSA-DRV had lower computational latency (on average 29.9% lower) and power consumption (on average 30.6% lower) than did a conventional sense amplifier design and reconfigurable assist sense amplifier. Thus, the proposed design can overcome the von Neumann bottleneck to facilitate high-speed, energy-efficient data processing, which is crucial for AI-based and other data-intensive applications.","PeriodicalId":13039,"journal":{"name":"IEEE Transactions on Circuits and Systems I: Regular Papers","volume":"72 8","pages":"4052-4063"},"PeriodicalIF":5.2,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144739823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, previous researches have primarily concentrated on super-regenerative amplifiers/oscillators, leading to limited insights into SRRs with inappropriate assumptions or dispensable operations, such as synchronous quench and baseband oversampling. This paper presents an improved general theory of super-regenerative reception in the linear mode that provides more design insights for digital communication. By analyzing the time-domain model of a general super-regenerative circuit, we derived a comprehensive frequency-domain model based on a convolution method, through which a concept of signal-lobe transfer function is introduced. Based on the proposed model, the effects of quench jitter and residual phenomenon are analyzed. Furthermore, an asynchronous quench method is introduced, which eliminates the requirement of synchronization between the modulated symbol and the quench signal, thus reducing the system complexity. To eliminate the baseband oversampling, especially for high-speed communications, main-lobe filtering and sub-sampling techniques are also proposed. To verify this general theory and proposed techniques, two SRRs with main-lobe filtering and sub-sampling were designed with ideal components and simulated using Cadence Virtuoso. The simulation results of two SRRs match with the proposed model very well. Overall, this paper provides a comprehensive analysis of super-regenerative reception for digital communication and offers valuable insights into its potentials and limitations.","PeriodicalId":13039,"journal":{"name":"IEEE Transactions on Circuits and Systems I: Regular Papers","volume":"72 6","pages":"2578-2591"},"PeriodicalIF":5.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The miniaturization and enhanced performance of the radiator is achieved through co-designing a ring oscillator and a multifunctional antenna. The multi-stage ring oscillator features a variable common-source (CS) stage, which is proposed to achieve a broad frequency tuning range. To enhance the performance of the proposed variable CS stage for terahertz (THz) oscillator, wideband load impedances for all harmonics are theoretically analyzed and recursively optimized. The multifunctional antenna integrates six key functions into a simple compact structure: 1) inherently embedding the ring oscillator within a symmetric layout to ensure uniform operation, 2) directly combining the desired third harmonic signals without bulky and lossy passive networks, 3) radiating the desired third harmonic, 4) suppressing unwanted even harmonics, 5) providing fundamental inductance for the ring oscillator, and 6) supplying DC bias at virtual ground. For experimental validation, a THz radiator including a four-stage ring oscillator and a multifunctional antenna, is co-designed and fabricated in 40 nm CMOS process.

Situational awareness through spectrum sensing, and AI/ML-enabled perception that recognizes behaviors, patterns, modulations, devices and waveforms is a crucial need for emerging autonomous/cognitive radio systems. This work describes measurable progress in the use of extremely low complexity approximate DFT algorithms as multi-beam beamformers in the digital domain for multibeam spatial RF beamforming. The paper begins with a longterm vision for intelligent spectrum awareness across wide bands and multi-directions with multi-chiplet system in package hardware acceleration of both beamforming, Fourier and AI/ML algorithms, followed by a focus account of specific progress with digital architectures and real-time prototype implementations across the 5.7–5.8 GHz band for 32 RF beams. A real-time temporal frequency resolution of 100 kHz across 100 MHz of baseband bandwidth is achieved, across 32 simultaneous fully-digital RF-beams, using a Xilinx Sx475 FPGA implementation. Details of multiplierless approximate DFT beamformers, automated modulation recognition algorithms using AI/ML, analog channelization, spectrum sensing and perception architectures are also discussed.

While most previous studies have focused on systems with a fixed discontinuous boundary, this paper examines systems with a variable discontinuous boundary. We develop a mathematical model based on Chua’s circuit and present numerical simulations of bursting oscillations under varying parameters. The impact of the translation of the discontinuous boundary (TDB) on the system’s topological structure and non-smooth bifurcations is analyzed. By combining the two-parameter bifurcation set of equilibrium points with the superposition diagram of the transformed phase diagram (TPD), we reveal mechanisms behind different bursting modes induced by the TDB. A Multisim-based simulation circuit is designed to validate the research results. It is found that the topology of the equilibrium branches of each subsystem remains the same during the TDB, but the number of smooth bifurcations changes due to the switching between subsystems. The TDB also alters the characteristics of the boundary equilibrium point, leading to the catastrophic disappearance or emergence of non-smooth limit cycles, which consequently changes the number of spiking oscillations. Moreover, the interaction of the slow passage effect (SPE) and the TDB causes the trajectory to remain in a delayed segment, affecting the number of spiking oscillations per period. Additionally, the TDB may lead to the disappearance of bursting oscillations, then the system exhibits a behavior similar to that of simple harmonic motion. Our study expands the scope of research on piecewise-smooth circuit systems.","PeriodicalId":13039,"journal":{"name":"IEEE Transactions on Circuits and Systems I: Regular Papers","volume":"72 6","pages":"2768-2777"},"PeriodicalIF":5.2,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
