Abstract
In this study,
different oscillator topologies have been realized with the help of a new
active element, Modified Current-Feedback Operational Amplifier (MCFOA). Only one
MCFOA element and a maximum number of five passive elements were used during
the design of the oscillator circuits. The oscillation criteria and oscillation
frequencies of the oscillator structures have been examined in detail. In addition, the non-ideality
effects of MCFOA block, due to the current and voltage tracking errors, were also
examined. The simulations were performed with SPICE program and 0.35 μm TSMC
CMOS technology parameters were used. The supply voltages are chosen as 1.65 V. It is ensured that the
oscillation condition criteria in the circuits does not affect the oscillation
frequency. Simulation results
are compared with theoretical results and presented in paper.

Abstract
Bu çalışmada yeni bir aktif eleman olan
iyileştirilmiş aktif geri beslemeli (MCFOA) blok devresi yardımıyla farklı
osilatör topolojileri gerçekleştirilmiştir. Bu osilastör yapıları
gerçekleştirilirken sadece bir adet MCFOA yapısı ve en fazla beş adet pasif
eleman kullanılmıştır. Gerçekleştirilen osilatör yapılarının osilasyon
kriterleri ve osilasyon frekansları detaylı olarak incelenmiştir. Ayrıca MCFOA
yapısındaki akım ve gerilim izleme hatalarından kaynaklanan idealsizlik
etkileri de ayrıca incelenmiştir. Simülasyonlar SPICE programı yardımıyla
yapılmış ve 0.35 µm TSMC CMOS teknoloji parametreleri kullanılmıştır. Ayrıca
kullanılan devrede besleme gerilimi olarak 1.65 V alınmıştır. Gerçekleştirilen devrelerde
osilasyon kriterlerinin osilasyon frekansı etkilemeyeck şekilde olmasına da
dikkat edilerek tasarımlar gerçekleştirilmiştir. Simülasyon sonuçları teorik sonuçlar ile
karşılaştırılmış ve makalede verilmiştir.
