Abstract

본 발명은 공급 전류원 제어의 연산증폭기에 관한 것으로서, 연산증폭기에 있어서, 바이어스단; 차동증폭단; 및 소정의 전압값 이하이면 2단 연산 증폭을 수행하고, 소정의 전압값 이상이면 소정의 증폭을 수행하며, 상기 바이어스단으로부터 커런트 미러 구조로 상기 차동증폭단에 전류를 공급하여 일점의 전압을 일정한 전압으로 유지하기 위한 회로단을 포함한다.The present invention relates to an operational amplifier for supply current source control, comprising: a bias stage; Differential amplifier; And performing two-stage operational amplification when the voltage is less than a predetermined voltage value, and performing a predetermined amplification when the voltage is equal to or greater than a predetermined voltage value. It includes a circuit stage for maintaining.

따라서, 상술한 바와 같은 커런트 미러를 추가해 줌으로써, 이득 및 주파수 특성의 향상을 꾀할 수 있는 효과를 제공한다.Therefore, by adding the current mirror as described above, the effect of improving the gain and frequency characteristics is provided.
