The proposed BVG-AVSPS consists of a novel bidirectional quadrature generator, four dual-function bidirectional amplifiers and two input/output matching networks. The proposed hybrid-based quadrature generator achieves low orthogonal amplitude and phase mismatches over a wideband with bidirectionality. Dual-function bidirectional amplifiers are employed to achieve either vector modulation or gain control functions in different operational directions. To improve the phase shifting accuracy during gain tuning, compensation transistors are employed in the dual-function bidirectional amplifiers to minimize additional phase variation. The proposed input/output networks based on L-type coupled inductors ensure proper impedance matching for both input and output in TX and RX modes.

This paper presents an innovative architecture for a continuously variable bandwidth filter using a fixed hardware. Our approach integrates a fixed finite impulse response filter between two arbitrary fractional delay filters implemented through a novel Farrow-equivalent-Newton structure. The proposed architecture provides a low-complexity implementation structure compared to the state-of-the-art approaches. A precise mapping equation for the edge frequencies of the filters generated from the proposed continuously variable bandwidth filter, in terms of a variable parameter called the resampling ratio, is also formulated.

Numerous Trojan detection approaches are in the literature. However, most of them are limited to netlist level identification and unable to explain the process variation issue in post-silicon chips. In this work, we propose a new detection technique with delay side-channel analysis that can detect all types of Trojans under the presence of high process variations. The technique is termed as zero delay deviation (ZDD) that is capable of diminishing the effect of all variations and other noise sources to identify the Trojan presence in chips. The ZDD approach is achieved by 1) a novel equal-delay circuit partitioning, 2) placing a highly secured camouflaged ring oscillator PUF per partition to generate equal-delay challenge-response pairs that delivers the knowledge of variation trends, 3) generating Identical Delay (ID) neighboring pairs for both, partitions and PUF designs that ensure nullifying the variation effects upon comparing them. The ZDD is examined through an intra-referencing of ID pairs with PUF-RD pairs in ISCAS’85 and 89 benchmarks. 10,000 virtual chips are generated by Monte Carlo simulation considering all physical characteristics of a real chip. Results demonstrate that the proposed approach can successfully detect Trojans even if it consists of a single gate. A comparison to the state-of-the-art shows the method superiority over others.","PeriodicalId":13039,"journal":{"name":"IEEE Transactions on Circuits and Systems I: Regular Papers","volume":"72 8","pages":"4153-4166"},"PeriodicalIF":5.2,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144739911","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}

This paper proposes an input phase control mechanism together with a cooperative asymmetric out-phased current load modulation technique. The cooperative asymmetric out-phased current load modulation can extend the output back-off range (OBO). The input phase control mechanism together with modified impedance transforming load modulation networks (LMNs) is used to widen the DPA bandwidth. An input coupled-line coupler is implemented to realize this phase requirement. For demonstration purposes, a DPA with an operating frequency from 1.7 GHz to 2.9 GHz and with a 9-dB OBO range is designed and fabricated using GaN HEMT devices. Continuous-wave measurements show that the implemented DPA exhibits a drain efficiency ranging from 54.5% to 75.6% at saturation and from 41% to 50.6% at 9-dB OBO across the operating bandwidth. When excited by a 20-MHz long-term evolution (LTE) signal with a 9-dB peak-to-average power ratio (PAPR), the implemented DPA achieves average drain efficiencies of 41%- 53.8% with an adjacent channel leakage ratio (ACLR) better than −48.1 dBc after digital predistortion (DPD).","PeriodicalId":13039,"journal":{"name":"IEEE Transactions on Circuits and Systems I: Regular Papers","volume":"72 6","pages":"2626-2638"},"PeriodicalIF":5.2,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170926","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 traditional modeling methods are difficult to balance the accuracy of the model and the simplicity of calculation and are not suitable for different switching frequency systems. In view of the above problems, this paper uses simplified discrete time mapping model to model the system. It combines the state space average model with the discrete time mapping model, which greatly improves the simplicity and accuracy of modeling. Taking the photovoltaic-energy storage system as an example, this paper analyzes the nonlinear behavior of the system and predicts the critical control parameters when the Hopf bifurcation occurs in the system. The eigenvalue sensitivity analysis is used to determine the eigenvalue change rate and change trend when the control parameters change, which provides guidance for the selection of parameters in practical applications. Finally, the high precision of the model is verified by simulation, and the applicability and effectiveness of the method in different switching frequency systems are verified by experiments.","PeriodicalId":13039,"journal":{"name":"IEEE Transactions on Circuits and Systems I: Regular Papers","volume":"72 6","pages":"2778-2791"},"PeriodicalIF":5.2,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170880","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}

A direct-modulation structure composed of the cross-coupled oscillator with the fast-switched film bulk acoustic resonator (FBAR) is used to enhance the frequency stability under fast OOK/BFSK modulation. To avoid extra phase-reversal circuitry, a polarity-swapped switching structure is employed in the differential branches of the modulator to achieve energy-efficient BPSK modulation, and this structure is also reused as a buffer stage for OOK/BFSK modulation to avoid the loading effect. In addition, an adaptive fast-switching technique is also proposed to improve OOK/BFSK modulation data rate and energy efficiency. The modulator is fabricated in a 180 nm CMOS technology. The free-running oscillation frequencies with two FBARs are 962 MHz and 990 MHz, and the measured phase noises are -137.3 dBc/Hz@1MHz and -137.1 dBc/Hz@1MHz, respectively.
