Abstract

Bu çalışmada, literatürde daha önce önerilen iki farklı salt MOSFET filtre devrelerinin devrenin gürültü performansları araştırılmıştır. Sunulan çalışmalardaki salt MOSFET filtrelerin gürültü performansları ne benzetim sonucu olarak ne de girişe aktarılan gürültü denklemleri elde edilmiştir. Sunulan filtreler yüksek frekanslarda çalıştığı için devrelerin gürültü performansları incelerken sadece ısıl gürültü göz önünde bulundurulmuştur. Literatürdeki analog filtreler ile adil bir karşılaştırılma yapılması için girişe aktarılan gürültü denklemleri elde edilmiştir. Gürültü benzetim sonuçları ile teorik sonuçlar uyum içinde olduğu gözlenmiştir.

Investigating Noise Performances of MOSFET-Only Filters

Abstract

In this work, noise performances of the previously presented two MOSFET-only filters have been investigated. Neither their noise simulation results nor their input referred noise equations have been obtained. Since the previously presented filters operate at high frequencies, the thermal noise is only taken into account when examining the noise performances of them. In order to make a fair comparison with analog filters in the literature, input referred noise equations of them have been found. Noise simulation results are in agreement with the theoretical results of them.

Keywords
