- Abstract
This paper presents a temperature/supply stable and resistorless voltage reference for high-precision portable electronic products. the reference obtains a good temperature coefficient over a wide temperature range through high-order curvature compensation. In order to reduce the temperature nonlinearity, the piecewise linear temperature curvature compensation circuit is used. The voltage reference is simulated with 55nm CMOS technology. It operates at the voltage of 2.5V and generates a stable voltage at 0.742V with a minimal temperature coefficient of 3.19ppm/ for temperature ranging from - 40 to 125 .
