A CMOS bandgap reference for high precision DACs

A CMOS bandgap reference for high precision DACs

In order to meet a high-speed, high-precision DAC design requirements. A practical reference voltage source is designed by the basic design principle of the bandgap reference voltage source, and a voltage reference circuit with fast start and high stability is obtained. The post-layout-simulation re...
