摘　　要：设计了一种基于恒压源控制的高稳定型恒流源，通过对元器件的合理选型以及对电路的优化设计，使得恒流源的稳定性可以达到0．1μA。给出了设计的理论推导和相关电路设计，对工程应用具有一定的指导意义。A constant high stable current source based on source of high pressure voltage is designed. The stability of the constant current source can be controlled to a microampere through the rational selection of components and the optimization of circuit design. The theoretical derivation of the design and the circuit design are posented. It has a certain guiding significance for engineering applications.
