Special Issue Information

Dear Colleagues,

The ability to sense, communicate, and harvest energy in a prevalent and continuous manner is fundamental to the next generation of artificial intelligence (AI), automotives, and medical devices. As the bridge between the physical and cyber worlds, analog mixed-signal (AMS) integrated circuits are a critical foundational technology. While micromachined sensors, transducers, and actuators provide the necessary conversion of signals and energy from one form to another, AMS circuits play the indispensable role of conditioning them with high precision and efficiency, which ultimately governs the proficiency of sensor systems. Furthermore, AMS computing is attracting growing attention as a new paradigm for deploying AI accelerators on the edge. As such, advanced design of integrated AMS electronics and microsystems with a strong emphasis on extreme energy and area efficiency provides the keystone toward ubiquitous sensing and intelligence. Accordingly, this Special Issue seeks to showcase research papers, communications, and review articles that focus on state-of-the-art AMS circuits and systems in the scope of smart sensor systems, covering topics of (1) ultra-low-power sensor readout circuits, sensor-driving circuits, and MEMS-CMOS codesigns; (2) high-efficiency solid-state and micromachined energy harvesting systems; (3) miniature medical instruments and imaging devices; and (4) energy-efficient AMS computing circuits.

We look forward to receiving your submissions!

Human body temperature is a fundamental physiological sign that reflects the state of physical health. It is important to achieve high-accuracy detection for non-contact human body temperature measurement. In this article, a Ka band (32 to 36 GHz) analog complex correlator using the integrated six-port chip is proposed, and a millimeter-wave thermometer system based on the designed correlator is completed for human body temperature measurement. The designed correlator utilizes the six-port technique to achieve large bandwidth and high sensitivity, and miniaturization of the correlator is achieved through an integrated six-port chip. By performing the single-frequency test and the broadband noise measurement on the correlator, we can determine that the dynamic range of input power of the correlator is −70 dBm to −35 dBm, and the correlation efficiency and equivalent bandwidth are 92.5% and 3.42 GHz, respectively. Moreover, the output of the correlator varies linearly with the input noise power, which reveals that the designed correlator is suitable for the field of human body temperature measurement. Then, a handheld thermometer system, with a size of 140 mm × 47 mm × 20 mm, is proposed using the designed correlator, and the measurement results show that the temperature sensitivity of the thermometer is less than 0.2 K.
