一种压控恒流源的设计

Design of a Voltage Controlled Constant Current Source

基于通用小功率运算放大器,进行输出级功率扩展,设计了一种压控恒流源,其输出电流恒定,并且可通过控制电压调节。采用混合集成电路工艺制造了样品电路,进行了功能验证,参数测试,达到设计要求。

Based on the general low power operational amplifier,the output stage power is expanded.A voltage controlled constant current source is designed in this paper.Its output current is constant and can be regulated by control voltage.The sample circuit is fabricated by hybrid integrated circuit technology,and the function verification and parameter test are carried out,which meet the design requirements.
