OTA를 이용한 오차 증폭기의 특성
Characteristic of Error Amplifier Using OTA
초록
This paper proposes an error amplifier circuit using OTA(Operational Transconductance Amplifier) which is the main constituent element in pulse width modulation circuit. The proposed OTA error amplifier circuit is featured by simple circuit configuration, excellent high frequency characteristics and bias current controlled output. Through the experiment of pulse width modulation circuit, the validity of the operation of the OTA error amplifier circuit is verified.
