Abstract
Purpose
The purpose of this paper is to propose a detailed analysis of a memristor-based differentiating circuit with buffering amplifier, a capacitor and a memristor.
Design/methodology/approach
The analyzed circuit is based on a resistor–capacitor differentiating scheme together with a buffering operational amplifier. In the proposed circuit, the resistor is replaced by a memristor element.
Findings
The considered circuit and its classical analog are investigated using a rectangular pulse sequence as input signal. A comparison between the derived results is made. An advantage of the proposed memristor circuit is the shortened duration, i.e. higher localization, of the output pulses of rectangular input pulses to be derived.
Originality/value
Differentiating circuits are important modules in radio-electronics. Because of their widespread usage, it is of higher interest that their new potential schematic realizations are analyzed. For the computer simulations, a previously proposed modified nonlinear memristor model is used. Several of the best and widely used basic memristor models are applied as well.
