Abstract

Bu çalışmada, Değiştirilmiş Akım Geriyönlü Geçiş-iletkenliği Kuvvetlendiricisi (Modified Current Backward Transconductance Amplifier-MCBTA) aktif elemanı kullanılarak yeni bir akım modlu dikgen sinusoidal osilatör (quadrature oscillator) devresi tasarımı gerçekleştirilmiştir.  Önerilen dikgen sinusoidal osilatör devresi iki adet MCBTA, iki adet bir ucu topraklı kapasite elemanı ve bir adet bir ucu topraklı direnç elemanından oluşmaktadır. Önerilen devrenin akım çıkış uçları yüksek çıkış empedansına sahiptir ve ard arda bağlanmaya uygun yapıdadır. Osilasyon şartı bir direnç elemanı ile ve/veya MCBTA aktif elemanının geçiş iletkenliği parametresi (g_m) ile kontrol edilebilmektedir.  Önerilen devrenin doğruluğu PSPICE simülasyonları gerçekleştirilerek gösterilmiştir. MCBTA aktif elemanının CMOS gerçeklemesi TSMC 0.25 µm üretim parametreleri için gerçekleştirilmiş ve simülasyon sonuçları elde edilmiştir.

CURRENT MODE QUADRATURE OSCILLATOR CIRCUIT DESIGN USING MCBTA ACTIVE COMPONENT

Abstract

In this study, a new current-mode quadrature sinusoidal oscillator circuit using modified current backward transconductance amplifier (MCBTA) are introduced. A new quadrature sinusoidal oscillator circuit employs two MCBTAs, two grounded capacitors and one grounded resistor. The current outputs of the proposed circuit provide high-frequency sinusoidal oscillation in quadrature at high impedance current output terminals of the MCBTAs. The oscillation condition of the proposed quadrature oscillator is controlled by one resistor and/or (g_m) transconductance value of MCBTAs. The validity of the proposed circuits is verified PSPICE simulations. CMOS implementation of the MCBTA is performed for TSMC 0.25 µm process parameters and simulation results are obtained.
