Abstract (2. Language): 
A new current-mode first order all-pass filter configuration is proposed and as it’s an application a current-mode quadrature oscillator circuit is also presented in this paper. The proposed circuit consists of a second generation current conveyor (CCII), two different type resistors and one type capacitors. Since the output of the filter exhibitslow output impedance, the synthesized filter can be cascaded without additional buffers.Furthermore, it does not impose any component matching constraint in analog signal processing circuits. To explore the performance of the proposed all-pass filter section, a new current-mode quadrature oscillator is implemented. The performances of the proposed all-pass filter as well as the quadrature oscillator are also investigated by applying sensitivity analysis to the both proposed circuits. Finally the theoretical results are verified with PSPICE simulations using a CMOS realization of CCII.

Abstract (Original Language): 
Bu makalede yeni akım modlu birinci dereceden tümgeçirenfiltre yapısıönerilmişve onun uygulaması olan akım modlu quadrature osilatör devresi gerçekleştirilmiştir. Önerilen devre ikinci nesil akım taşıyıcı (CCII), iki farklı direnç ve bir kondansatörden oluşmaktadır. Filtrenin çıkışı düşük empedansa sahip olduğundan sentezlenen devre kaskat olarak ek bir devre istemeden bağlanabilmektedir. Ayrıca bu devrenin Analog işaret işleme devrelerine uyarlanmasında her hangi bir zorlukla karşılaşılmamaktadır. Önerilen tümgeçirendevrenin performansını incelemek için yeni akım modlu quadrature osilatör devresi gerçekleştirlmiştir. Tümgeçirendevrenin performansını incelerken olduğu gibi,quadrature osilatörün performansını incelerken de duyarlılık analizi yapılmıştır. Teorik sonuçlar CMOS ile CCII gerçekleştirilerek PSPICE simulasyonu ile doğrulanmıştır.
