INDUCTOR SIMULATION WITH OPERATIONAL DEVICES

Abstract

In this study, inductor simulation by using operational devices, Opamp, OTA, and CC, is investigated. After covering main inductor simulation circuits, they areall tested in a passive band-pass filter with a center frequency of 1MHz using PSpice software. The filter characteristics thus obtained are compared to that of the original passive filter. As a result, the active filters tested are shown to be equivalents of the passive one with some performance differences.

Abstract

Bu çalışmada işlemsel devre elemanları kullanarak endüktans simulasyonu üzerinde durulmuştur. Opamp, OTA ve CC kullanan endüktans simülasyon devreleri verildikten sonra, bu devreler kullanılarak pasif bir bant-geçiren filtrenin L elemanının fo=1MHz için PSPICE yazılımı ile simülasyonu yapılmıştır. Elde edilen filtre karakteristikleri orijinal RLC devresininkiyle karşılaştırılarak ele alınan devrelerin endüktans simülasyonunda başarıyla kullanılabileceği gösterilmiştir
