Recently, the research group led by Associate Professor Duan Quanzhen from the School of Integrated Circuits at Sun Yat-sen University has achieved notable advancements in the realm of analog integrated circuit design. Their findings have been successively published in the prestigious international journal IEEE Transactions on Circuits and Systems—I: Regular Papers (TCAS-I). The two studies present innovative approaches for designing low-power level shifter circuits and high-precision MEMS capacitance-to-voltage conversion technology, respectively. The first study significantly cuts down on power consumption by refining the circuit structure, while the second enhances the conversion accuracy of MEMS sensors through improved signal processing algorithms. These relevant achievements offer crucial technical backing for the design of Internet of Things (IoT) sensors and Micro-Electro-Mechanical Systems (MEMS) chips, carrying substantial importance for driving forward the development of low-power smart sensing devices and high-precision industrial sensors.
