The physical world we live in is analog. The role of analog electronics in modern information and communication technology (ICT) and computing systems includes such aspects as physical world sensing and interaction, computing, control, data conversion, communication, power supply, and measurement. Analog microelectronics devices, mainly analog integrated circuits , are key components in almost all digital-centric systems today, and are critical to the future development of information technology. In order to achieve the infrastructure construction goals of the information society, such as the new generation of ICT, industry 40, and the internet of things represented by the 5G and 6G communications, the primary and necessary condition is a fundamental breakthrough through analog hardware to achieve intelligent sensing, cognition, and processing of the physical world and machine interaction. This requires analog electronics technology to conduct research in wireless signal chain integrated circuits, computing paradigms and architectures, high-precision perception and control, as well as design, process and packaging test technologies for analog microelectronics, and meeting application-specific requirements, addressing such areas as computing paradigm and architecture innovations, compressed sensing, process technologies required for new architecture innovations, and the challenges posed by the development of high-band integrated circuits such as millimeter wave and terahertz. This paper discussed recent research advances at the frontiers of analog microelectronics and application technologies in terms of wireless signal chain integrated circuits, analog technologies in edge machine learning, high-precision sensing and control, and important process innovations, showing the key future trends in analog electronics.
