Memristör tabanlı kaotik rössler devresi gerçeklemesi

Öz

Bu çalışmada kaotik Rössler diferansiyel denklem kümesinin elektronik gerçeklemesi için memristör tabanlı yeni bir analog devre önerilmştir. Kaotik faz portreleri ve çatallanma diyagramları için matematiksel analizler ve SPICE simülasyonları yapılmışır. Önerilen sistem ticari olarak piyasada bulunan aktif ve pasif elemanlar kullanılarak bord üzerinde gerçeklenmiş ve deneysel çalışma yürütülmüştür. Elde edilen deneysel sonuçlar, matematiksel analizler ve simülasyon sonuçları ile uyumludur. İhtiyaç duyulan memristans karakteristiğini sağlayacak olan bir memristans simülatörü devresi önerilmiş, ve ona ait non-lineer dinamikler frekansa bağlı histeresis eğrileri incelenerek memristif yapısı doğrulanmıştır.
