Abstract
A bridge resistance deviation-to-frequency (BRD-to-F) converter is presented for interfacing resistive sensor bridges. It consists of a linear operational transconductance amplifier (LOTA), a current-controlled oscillator (CCO). The prototype converter was simulated using commercially available discrete components. The result shows that the converter has a conversion sensitivity amounting to 16.90 kHz/
저항형 센서 브리지를 인터페이싱 하기 위한 저항 편차-주파수 변환기를 제시하였다. 이 변환기는 선형 연산 트랜스컨덕턴스 증폭기(linear operational transconductance amplifier: LOTA)와 전류-제어 발진기(current-controlled oscillator: CCO)로 구성된다. 제시된 변환기를 상업용 개별 소자들을 이용하여 SPICE 시뮬레이션 하였다. 시뮬레이션 결과는, 변환기가 16.90 kHz/
