Abstract

In this paper, two new lossless floating capacitance multipliers (FCMs) are designed. These FCMs consist of two dual-output second-generation current conveyors (DO-CCIIs). In the designed FCMs, two resistors and a capacitor are used. The resistors of the proposed FCMs are grounded. Nevertheless, the capacitors of the FCMs are floating. The proposed circuits can be electronically adjusted if current controlled DO-CCIIs are employed instead of the DO-CCIIs in the proposed lossless FCMs. Furthermore, passive element matching conditions do not necessary for the proposed circuits. The proposed FCMs are tested in the second-order passive filter. The SPICE program is carried out for all the simulations while utilizing the parameters of the 0.18 µm CMOS technology.

İki DO-CCII Tabanlı Kayıpsız Yüzen Kapasite Çarpan

Abstract

Bu çalışmada, iki yeni kayıpsız yüzen kapasite çarpanı (FCM) tasarlanmıştır. Bu FCM devreleri, iki adet çift çıkışlı ikinci nesil akım taşıyıcı (DO-CCII) ile tasarlanmıştır. Tasarlanan FCM devrelerinde iki direnç ve bir kondansatör kullanılmıştır. Önerilen FCM devrelerinin dirençleri topraklanmıştır. Buna rağmen, önerilen devrelerde kullanılan kondansatörler yüzen seçilmiştir. Önerilen kayıpsız FCM devrelerindeki DO-CCII aktif elemanları yerine akım kontrollü DO-CCII aktif elemanları kullanılırsa, önerilen devreler elektronik olarak ayarlanabilir olur. Ayrıca, önerilen devreler pasif eleman eşleştirme sorunlarından muzdarip değildir. Önerilen FCM devreleri ikinci dereceden pasif filtrede test edilmiştir. Tüm simülasyonlar, 0.18 µm CMOS teknolojisinin parametreleri kullanılarak SPICE programı aracılığı ile gerçekleştirilmiştir.
