Recently, the research team helmed by Associate Professor Chen Mingyi from the School of Integrated Circuits at Shanghai Jiao Tong University has achieved a remarkable milestone in the realm of precision sensing interface chips. The team has introduced an innovative on-chip pseudo-resistor precision automatic calibration technique. This method is particularly suited for precision sensing applications, including brain-computer interfaces and underwater acoustic signal detection systems. By addressing critical technical hurdles, this advancement paves the way for the large-scale, cost-effective production of precisely adjustable on-chip ultra-high resistance resistors.
