Design of Low Power High Stability Constant Current Source System
In this paper, a high stability constant current source system is designed, and its output current range is - 100mA~100mA. Firstly, based on the series negative feedback circuit to achieve steady current design, external DAC to realize the adjustment function, then, made a precision sampling resistor to achieve high stability, designed and tested a high stability voltage reference source, and developed STM32 peripheral resources to Its functions are enriched, and finally after long-term measurement, the current stability is better than 2ppm. This design has the advantages of simple structure, strong operability, and high stability.
