Abstract

The invention discloses a floating geomagnetically controlled memristor simulator based on a transconductance operational amplifier. comprising a port a, a port b, a transconductance operational amplifier U1, a transconductance operational amplifier U2, a current feedback operational amplifier U3, a voltage feedback operational amplifier U4, a capacitor C1, a resistor R1, a resistor R2, a resistorR3, a resistor R4, a resistor R5, a resistor R6, a resistor R7, a resistor R8, a resistor R9, a resistor R10 and a resistor R11.The model of the transconductance operational amplifier U1 is LM13600,and the model of the transconductance operational amplifier U2 is LM13600. The electrical characteristics of the floating geomagnetically controlled memristor simulator port a and the floating geomagnetically controlled memristor simulator port b are equivalent to the port characteristics of a magnetically controlled memristor, one end is not required to be grounded, and the floating geomagnetically controlled memristor simulator port a and the floating geomagnetically controlled memristor simulator port b can be widely applied to design and testing of memristor circuits (memristor chaotic circuits, memristor oscillating circuits and the like).

Description

technical field [0001] The invention relates to the field of novel circuit element simulator construction, in particular to a magnetron memristor simulator based on a transconductance operational amplifier. Background technique [0002] In 1971, Professor Cai Shaotang of the University of California, Berkeley, starting from the completeness of circuit theory, predicted that in addition to resistance, capacitance and inductance, there was a fourth passive basic circuit element that represented the relationship between charge and magnetic flux, and named it For the memristor (memristor). In 2008, HP Labs published research results in the journal Nature, announcing the physical realization of a two-terminal device with memristor characteristics. The breakthrough of Hewlett-Packard Labs has aroused widespread concern in academia and industry, setting off an upsurge of people's research on memristors. [0003] A memristor is a nonlinear resistor whose resistance value can chang...
