Passive Filters for Nonvolatile Storage Based on Capacitive-Coupled Memristive Effects in Nanolayered Organic–Inorganic Heterojunction Devices
Source abstract
Abstract
It is well-known that the reprogrammable device is one of the important needs for circuit design. In this paper, nanolayered TiO2 and maple leaves (ML) are combined to form a functional layer (TiO2-ML) inside memristive devices, which demonstrate both the capacitive effect and the nonvolatile storage capability. When the voltage increases from zero, the device first enters a capacitive-coupled memristive state at low voltage before switching to a normal memristive state at a higher voltage. The existence of the capacitive behavior results in a nonzero-crossing I–V characteristic different from the zero-crossing curve observed in normal memristive device. Utilizing this capacitive-coupled memristive behavior, we design a low power passive filter with applications toward reprogrammable analog circuit designs, paving a path toward a multifunctional nanodevice in the future.
