摘要
Abstract
This paper presents an ultra-high precision voltage reference chip that operates stably with various capacitive loads without requiring an external capacitor.By incorporating a bandgap reference with built-in trimming structure and an output voltage feedback network,combined with dynamic compensation and overcurrent protection circuits,the design achieves high accuracy,low temperature drift,and low dropout voltage.After fabrication in a 0.18 μm CMOS process,the test results show that the output voltage accuracy of the chip is better than 2%,the temperature coefficient is less than 35 ppm/℃,and the input and output voltage difference is less than 1mV.It is suitable for high-demand occasions such as battery power supply equipment,medical electronics and automotive data acquisition systems.关键词
