Usually, the delay of usual multipliers is high due to the number of computations, consequently; the overall speed of circuits become less, and increases power consumption. The performance of Digital Signal Processing (DSP) processors is frequently dependent on the Multiplier and Accumulator (MAC) unit, and three parameters determine it, namely power, area and speed. However, the performance of the conventional MAC is not good when the number of bits increases and also using several multiplication factors increases the power consumption. So, to reduce the compressor size for working with a higher level of bits in lower power and low area consumption, this paper proposes a new architecture for an effective MAC unit. In the proposed architecture, the Peres logic gates are applied in the third compression stage for reducing the power compression and delay. The outcomes demonstrate that the suggested design has high speed and low MAC unit area consumption. Furthermore, the increase in the compressor size is not affecting the system operations. The proposed architecture can be applied for future DSP system to get efficient performance.</p></div>","PeriodicalId":7827,"journal":{"name":"Analog Integrated Circuits and Signal Processing","volume":"124 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144140165","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}

Preamble detection is a critical step in synchronizing received signals after demodulation, yet traditional methods—such as correlation and Hamming distance techniques—suffer from high power consumption and computational complexity. To address these challenges, this paper proposes a novel majority voting-based pattern recognition method that enhances detection accuracy while reducing energy consumption. By leveraging majority voting, our approach mitigates noise effects and improves signal robustness, enabling more efficient preamble detection across varying signal-to-noise ratios (SNRs). The proposed method is implemented in both CMOS-based and hybrid memristor-CMOS architectures, where the hybrid design incorporates dedicated complementary circuits to further optimize power efficiency and reduce silicon area utilization. Unlike conventional CMOS-only implementations, our hybrid approach reduces redundant computations and enhances energy efficiency, making it well-suited for resource-constrained applications. Performance evaluation demonstrates significant improvements over existing techniques, highlighting the potential of memristor-CMOS hybrid technology in low-power, high-speed communication systems.</p></div>","PeriodicalId":7827,"journal":{"name":"Analog Integrated Circuits and Signal Processing","volume":"124 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144108493","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}

The integration of a communication system with sensors and actuators enables the formation of a closed-loop system responsible for maintaining the desired state. This study investigates the suitability of a universal asynchronous receiver and transmitter (UART) for communication in implantable medical devices. The UART protocol is selected due to its advantage of allowing different frequencies for the receiver and transmitter, which facilitates communication between different peripheral devices and the core processing system.
