The Dynamic Tunability of Memristor-Based Active Filters

Area of Science:

• Electronics
• Materials Science
• Analog Circuit Design

Background:

• Memristors have spurred significant theoretical research, often relying on simulations.
• Existing research lacks practical integration of memristors into commercial analog circuits.
• Previous studies have not addressed real-time programming of memristor-based analog systems.

Purpose of the Study:

• To present a practical, experimental solution for programming commercial memristors.
• To implement a memristor in a tunable active bandpass filter.
• To enable dynamic, in-operation programming of analog filter central frequencies.

Main Methods:

• Developed an automated programming solution for a commercially available memristor.
• Integrated the programmed memristor into an active bandpass filter prototype.
• Conducted experimental measurements on the circuit prototype to validate performance.

Main Results:

• Successfully embedded a commercial memristor into an analog circuit prototype.
• Demonstrated real-time, in-operation programming of the active bandpass filter's central frequency.
• Experimental results show promising performance for memristor integration in analog systems.

Conclusions:

• The developed method facilitates the practical application of memristors in analog electronics.
• Continuous, on-the-fly tuning of analog filters is achievable using memristors.
• This work opens new avenues for memristor utilization in commercial analog systems.
