1V, 12ppm/°C Bandgap Reference Circuit Design in CMOS Technology

Paper presents a design methodology for a high precision bandgap reference voltage circuit designed in 65 nm CMOS technology. The proposed structure achieves a nominal output voltage of 1 V with a low temperature coefficient of 11.89 ppm/°C, ensuring stability across a temperature range from 0-100 °C. Key performance metrics include a power supply rejection ratio of -51 dB and robust operation over a supply voltage range of 1.6-2.5 V, making it suitable for power management in low energy-harvesting applications.
