Abstract

A systematic synthesis process is described lot the simulation of current-controllable inductors using operational transconductance amplifiers (OTAs). The process is used to obtain three circuits; two are believed It) be novel. The process is also applied to design current-controllable frequency-dependent negative resistances (FDNRs). Operation principles of designed circuits are presented and experimental results are used to verify theoretical predictions. The results show close agreement between predicted behavior and experimental performance. The application of a FDNR to a current-controllable band-pass filter is also presented.

OTA를 이용한 전류-제어 인덕터를 시뮬레이션하기 위한 체계적인 합성 과정을 기술했다. 그 합성 과정을 통해 세 개의 시뮬레이티드 인덕터를 설계했고, 그 중에서 두 개는 새롭게 설계된 것이다. 또한, 이 합성 과정을 전류-제어 FDNR 설계에 적용했다. 설계된 회로들의 동작 원리를 제시했고, 실험을 통해 설계 이론의 타당성을 증명했다. FDNR을 전류-제어 대역-통과 여파기에 응용한 예도 제시했다.
