A 16.28 ppm/ C Temperature Coefficient, 0.5V Low-Voltage CMOS Voltage Reference with Curvature Compensation
This paper presents a CMOS voltage reference designed for low-voltage operation (0.5V) with excellent temperature stability across a wide range (-40°C to 130°C). The design uses mutual compensation of PTAT and CTAT currents, enhanced by curvature compensation, to achieve a temperature coefficient of 16.28 ppm/°C and low line sensitivity.
