The College of Integrated Circuits at Nanjing University of Aeronautics and Astronautics has made a significant leap forward in the realm of high-performance voltage reference chips. Focusing on application scenarios like high-voltage power management, battery management systems, and power device drivers, the research team has successfully designed a fully integrated, single-stage high-voltage voltage reference chip. This chip stands out for its remarkable characteristics: a notably low temperature coefficient (28.71 ppm/°C), exceptionally low line sensitivity (0.000006%/V), and a swift startup time in the microsecond range (35 μs). The outcomes of this groundbreaking research have been featured in the IEEE Journal of Solid-State Circuits (JSSC) in 2026, with the paper entitled “A 28.71-ppm/◦C Voltage Reference With 0.000006%/V Line Sensitivity and 35 µs Startup Time.”
