Experimental Comparison of Frequency Analysis of Active and Passive Filter Circuits Designed By Using Memristor Instead of Resistor

Öz

In this study, the emulator circuit proposed by Mutlu et al., which gives a stable output curve in terms of application was used. The quality factor, cut-off frequencies and bandwidths of the circuit on passive and active filters were evaluated. It was observed that the quality factor of memristor-based filters was higher because the memristor is self-excited at low frequency points (≤ 100Hz). At high frequencies, it was observed that there was no positive effect since the output response of both active and passive filter circuits based on memristor behaved like a linear resistor.

Direnç Yerine Memristor Kullanılarak Tasarlanan Aktif ve Pasif Filtre Devrelerinin Frekans Analizlerinin Deneysel Karşılaştırılması

Öz

Bu çalışmada Mutlu ve diğerleri tarafından önerilen ve uygulama açısından kararlı bir çıkış eğrisi veren emülatör devresi kullanılmıştır. Pasif ve aktif filtrelerde devrenin kalite faktörü, kesim frekansları ve bant genişlikleri değerlendirilmiştir. Memristor düşük frekans noktalarında (≤ 100Hz) kendinden uyarılı olduğu için memristor tabanlı filtrelerin kalite faktörünün daha yüksek olduğu gözlemlenmiştir. Yüksek frekanslarda, hem aktif hem de pasif filtre devrelerinin memristör temelli çıkış tepkisi lineer bir direnç gibi davrandığından dolayı pozitif bir etkinin olmadığı gözlemlenmiştir.
