This paper demonstrates the use of a charge-controlled memductor for improving the performance of proportional-integral-derivative (PID) controllers. Firstly, the behavioral model of a PID controller based on current-feedback operational amplifier is

This paper address the multilevel image segmentation by merging Gaussian mixtures models (GMM) and Differential Evolution (DE) with constraints handling. Since the estimation of parameters associated to GMM is a complex task, DE is used to estimate t

New models based on pathological elements are introduced to describe the behavior of current- and voltage-mirrors with multi-outputs. To do so, simple element stamps for a current-controlled current source and a voltage controlled voltage source have

This work proposes a simple transformation methodology of normal nonlinear resistors/conductors to their inverted topologies in their floating and grounded versions (NNR/C). It is demonstrated that inverted topologies can also be configured as increm

A technique for reducing the offset at the frequency-dependent pinched hysteresis loop of memristor emulator circuits is introduced. The technique involves at integrating two DC voltage sources in the emulator circuits, keeping not only the circuit s

This paper provides a novel configuration to design a multi-scroll chaotic oscillator employing unity-gain cells. The inclusion of multi-breakpoints to create a high-order negative nonlinear resistor is realized by the parallel combinations of basic
