Abstract
In this paper, a large dynamic range floating memristor emulator ( LDRFME ) with equal port current restriction is proposed to be achieved by a large dynamic range floating voltage-controlled linear resistor ( VCLR ) . Since real memristors have not been largely commercialized until now, the application of a LDRFME to memristive systems is reasonable. Motivated by this need, this paper proposes an achievement of a LDRFME based on a feasible transistor model. A first circuit extends the voltage range of the triode region of an ordinary junction field effect transistor ( JFET ) . The idea is to use this JFET transistor as a tunable linear resistor. A second memristive non-linear circuit is used to drive the resistance of the first JFET transistor. Then those two circuits are connected together and, under certain conditions, the obtained “ resistor ” presents a hysteretic behavior, which is considered as a memristive effect. The electrical characteristics of a LDRFME are validated by software simulation and real measurement, respectively.
