In this work, a third-order quadrature
oscillator circuit is presented by using an inverting current feedback
operational amplifier (ICFOA), an active element that has attracted
considerable attention in recent years. The topology consists of two ICFOA,
three capacitors and three resistors by connecting a voltage mode second-order
low-pass filter and a voltage-mode integrator with a cascaded closed loop. The
workability of the circuit is verified by PSPICE simulation program and it is
seen that the simulation results verify the theory and the proposed circuit has
good performance. The theoretical cut-off frequency is 3,979MHz and the cut-off
frequency measured after the simulation is 3,933MHz. In the simulation, 0,35 μm MOSIS parameter set and ICFOA
CMOS structure are used. The proposed circuit power consumption is 4,83mW.

Öz

Bu çalışmada, son zamanlarda oldukça fazla
dikkat çeken bir aktif eleman olan Terslenmiş Akım Geri Beslemeli İşlemsel
Yükselteç (ICFOA) kullanılarak üçüncü dereceden quadrature osilatör devresi
sunulmuştur. Topoloji iki adet ICFOA, üç adet kapasitör ve üç adet direnç olmak
üzere gerilim modlu ikinci dereceden alçak geçiren filtre ve gerilim modlu
integratör yapısının kaskat bağlanıp kapalı çevrim oluşturması ile elde
edilmiştir. Sunulan devrenin çalışabilirliği PSPICE benzetim programı ile
denenmiş ve teorik sonuçlar ile örtüştüğü görülmüştür. Teorik kesim frekansı 3,979MHz ve benzetim sonucu
ölçülen kesim frekansı ise 3,933MHz’dir. Benzetimde 0,35 μm MOSIS parametre seti ve ICFOA
CMOS yapısı kullanılmıştır. Önerilen devrenin güç tüketimi 4,83mW’dır.
