摘要
提出用运算放大器构成压控恒流源负载电流公式,从恒流源内阻和形成输出电流误差两个方面。
This article proposes a construction of a load current formula of voltage controlled constant-current sources with operational amplifiers, and provides the analytical results of constructing constant-current sources with operational amplifiers in term of constant current resistance and output current error.
