Mixed Signal & RF Circuit Innovations

Abstract

The rapid growth of wireless communication, Internet-of-Things (IoT), and high-speed digital systems has driven unprecedented demand for innovative mixed-signal and radio frequency (RF) circuits. Mixed-signal circuits, which integrate analog and digital components, serve as the backbone for converters, sensors, and communication devices, while RF circuits are crucial for high-frequency wireless communication. This paper reviews recent innovations in mixed-signal and RF circuit design, highlighting novel architectures, emerging materials, and fabrication techniques. The study emphasizes performance optimization strategies, including power efficiency, linearity, noise reduction, and miniaturization, alongside trends in 5G and beyond wireless systems. Challenges, future directions, and practical applications in consumer electronics, automotive systems, and IoT devices are also discussed.
