Given lattice defects, GaAs pseudomorphic high electron mobility transistor (pHEMT) technology faces difficulties in realizing P-channel metal oxide semiconductor devices, necessitating new circuit structures to achieve the functionality of traditional VRs. To leverage the superior RF performance of compound semiconductors in implementing RF transceiver systems-on-chip, this paper proposes a VR based on GaAs pHEMT technology. The proposed VR circuit was fabricated and tested using a 0.15 μm GaAs pHEMT process. The test results demonstrated that the designed VR circuit exhibits a current load capability of 17 mA, a temperature coefficient of 186 ppm/℃, and a power line regulation of 22.5 mV/V.

These communications have to taken in to account security and privacy issues also. The aim of this research work is to provide secured cryptographic techniques to help the vehicles in obtaining necessary keys and information from Roadside Units (RSU), the data network, or from other vehicles while also ensuring a highest security in different ways of vehicular communication (V2I, V2V, and V2N). One of the many cryptographic methods that provide the solution to the objective is Elliptic Curve Cryptography (ECC). The fundamental operations of ECC such as point multiplication and point addition are carried out for 256-bits; also the proposed ECC processor follows the Koblitz curve secp256k1. “Divide and Conquer” is being followed in Karatsuba algorithm to increase speed of multiplication process. The incorporation of Pipelining also increases the speed of the multiplication on the ECC processor with additional area overhead. The novel Karatsuba ECC processor operates at a clock frequency of 238.40 MHz, computing point multiplication of 256-bit in 0.937 ms, throughput of 273.21kbps and area is 8.42 k slices in a FPGA Virtex-7. Integrating Pipelining in the proposed system increases the clock frequency up to 7.97%. Because of it, the time consumption is reduced by 9.90% and throughput is increased by 10.99%. This novel ECC processor performs well compared to the existing methods in terms of area-delay product, operating frequency, throughput and area.</p></div>","PeriodicalId":7827,"journal":{"name":"Analog Integrated Circuits and Signal Processing","volume":"123 3","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143865507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the conductivity of a memristor depends strongly on the amount and direction of the flowing charge through it, and it is primarily due to its intrinsic asymmetry. This phenomenon becomes disadvantageous and a massive hindrance to consider memristors in some biomimetic networks, such as memristive grid networks, where sensitivity of direction is important. This drawback can be avoided by using memristor fuse which is formed by connecting two identical memristors anti-serially. To effectively compare the polarity reversal effect of these circuit elements, a network of 2 RC cells in the form of passive neurons coupled by a memristor and then a memristor fuse is considered, thereby allowing to observe and compare the interaction of these circuit elements bidirectionally. The system is studied analytically and the result is visualized in the phase plane. The comparison is done by observing the evolution patterns of the trajectories with respect to the direction of flow of the charge through these circuit elements. In terms of functionality as demonstrated in this paper, the memristor fuse shows a promising symmetry with respect to the quantity and direction of the flowing charge through it.</p></div>","PeriodicalId":7827,"journal":{"name":"Analog Integrated Circuits and Signal Processing","volume":"123 3","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Radiation of Greenhouse gases in the atmosphere can be diminished by the utilization of EVs. The charging component is essential for PEVs, as they require electricity from the power grid to charge their batteries. With the appropriate control, the existing charger’s converter architecture can offer additional functionalities. The expansion of Off-board fast-CS is the primary cause of the widespread utilization of EVs. The demand for load increases when the EV battery is charged from the grid. This study examines the application of a V2G-enabled bidirectional off-board EV battery charger using the HBIAO and AIChOa algorithm. The HBIAO algorithm inherits the characteristics and features of Honey Badger and Aquila Optimization Algorithm, while AIChOa algorithm inherits the features of Sooty Tern Optimization Algorithm and Chimp Optimization Algorithm (ChOA). The hybrid optimization algorithms assist in the achievement of global optimal solutions, neglecting the local optimal solutions. The proposed EV charger is modeled and simulated in MATLAB/Simulink, and the controller’s efficiency is validated. The simulation findings show that the system can function efficiently compared to various traditional methodologies. With different simulation and testing outcomes, quick dynamic reactions and excellent steady-state system performances can be demonstrated.</p></div>","PeriodicalId":7827,"journal":{"name":"Analog Integrated Circuits and Signal Processing","volume":"123 3","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
