INVERTING CURRENT FEEDBACK OPERATIONAL AMPLIFIER AND ITS APPLICATIONS TO MOS-C CIRCUIT REALIZATION

Öz

In this paper, an active element called inverting current feedback operational amplifier (ICFOA) is described. CMOS implementations of ICFOA are included. It has been shown that this building block is very suitable for MOS-C realization of circuits. As the application examples, MOS-C implementation of Tow-Thomas biquad, Kerwin-Huelsman-Newcomb biquad, first order allpass filter and quadrature oscillator using ICFOA are presented. Theoretical analysis is verified by PSPICE simulations

TERSLENMİŞ AKIM GERİ BESLEMELİ İŞLEMSEL YÜKSELTEÇ VE MOS-C DEVRE GERÇEKLEMESİ UYGULAMALARI

Öz

Bu çalışmada, terslenmiş akım geri beslemeli işlemsel yükselteç (TAGBİY) olarak isimlendirilen bir aktif eleman tanıtılmıştır. TAGBİY’in CMOS gerçeklemeleri verilmiştir. Bu yapı bloğunun, devrelerin MOS-C gerçeklemeleri için çok uygun olduğu gösterilmiştir. Uygulama örnekleri olarak TAGBİY kullanan Tow-Thomas ve Kerwin-Huelsman-Newcomb süzgeçleri ile birinci dereceden tüm geçiren süzgeç ve salıngaç devreleri sunulmuştur. Teorik analizler PSPICE benzetim sonuçları ile doğrulanmıştır
