Abstract
제어 전류 발생회로를 공개한다. 그 회로는 기준 전압을 Vref, 저항값을 R, 공급되는 전류를 Ir, N비트 디지탈 데이타를 D0∼DN-1이라 할 때, 하기 식에 의해 디지탈 데이타에 따라 대응 전압 V0을 갖는 아날로그 신호로 변환 출력하는 디지탈-아날로그 변환부;The control current generation circuit is disclosed. The circuit has an analog voltage having a corresponding voltage V 0 according to the digital data according to the following equation when the reference voltage is V ref , the resistance value is R, the current supplied is Ir, and the N bit digital data is D 0 to DN −1 . A digital-analog converter for converting and outputting the signal;
상기 디지탈-아날로그 변환부로부터의 아날로그 신호의 전압 V0에서 기준 전압 Vref과의 전압차를 전류로 변환 출력하는 전압-전류 변환부를 구비한 것을 특징으로 한다.And a voltage-current converter configured to convert a voltage difference from the voltage V 0 of the analog signal from the digital-analog converter to the reference voltage V ref into a current.
