CMOS inverter tabanlı karşılaştırıcı devrelerinin incelenmesi

Abstract

In this study, the performance of the CMOS inverter circuit with active load, which can be used as a comparator structure in analogue digital converter circuits, is investigated with respect to other CMOS inverter circuits by using 0.25 mu m CMOS technology library in Cadence Virtuoso 6.13 design program. As a result of the analyzes made, it is seen that the proposed structure only consumes 1,041 uW and the delay time is 36.11 ps. The power dissipation, which the proposed design consumes, is significantly lower than the other designed CMOS inverter circuits. Therefore, when the proposed architecture is used in the comparator block of high-speed parallel analogue digital converters, power consumption is likely to decrease.

Yapılan bu çalışmada, Cadence Virtuoso 6.13 tasarım programında 0.25µm CMOS teknoloji kütüphanesi kullanılarak, analog sayısal dönüştürücü devrelerinde karşılaştırıcı yapısı olarak kullanılabilecek olan aktif yüklü cmos inverter devresinin diğer cmos inverter devrelerine göre performansları incelenmiştir. Yapılan analizler sonucunda, önerilen yapının sadece 1.041 µW güç harcadığı ve gecikme süresinin de 36.11 ps olduğu görülmüştür. Önerilen yapının harcamış olduğu güç miktarı, diğer tasarımlanan cmos inverter devrelerinden oldukça düşüktür. Dolayısıyla önerilen yapının yüksek hızlı paralel analog sayısal dönüştürücülerin karşılaştırıcı bloğunda kullanıldığında güç tüketiminin azalacağı görülmektedir.
