TLDR
An amplifier circuit whose magnification is precisely adjustable and an active memristor-filter whose cut-off frequency and phase are adjustable as well is presented, which provides a new way for the integrated circuit design in the future.Abstract:
Based on the electrical properties of memristor, the spintronic memristor is introduced into analog circuit design. Through programming the memristor by pulse signals, a programmable memristor potentiometer is designed in this paper. The potentiometer has the advantages of simple structure, small volume and continuous variable dynamic range. Based on the potentiometer above, this paper presents an amplifier circuit whose magnification is precisely adjustable and an active memristor-filter whose cut-off frequency and phase are adjustable as well. The circuit is characterized with smaller size, higher integration and lower power consumption, and its correctness and feasibility are verified by SPICE simulation. The research in this paper will promote the application of memristor in analog circuit, in addition, the performance of programmable memristor-analog circuit is satisfactory, which provides a new way for the integrated circuit design in the future.read more

Memristive devices and systems
Leon O. Chua,Sung-Mo Kang +1 more
TL;DR: In this article, a broad generalization of memristors to an interesting class of nonlinear dynamical systems called memristive systems is introduced, which are unconventional in the sense that while they behave like resistive devices, they can be endowed with a rather exotic variety of dynamic characteristics.
