Abstract

The invention discloses an arc tangent trigonometric function voltage-controlled memristor circuit model. An integrated operational amplifier U1 is connected with an input end, namely a voltage and current test end of a memristor; the integrated operational amplifier U1 is used for realizing inverse amplification operation and integral operation, outputting a signal after integral operation and finally solving a state variable for controlling a memristive value, and the integrated operational amplifier U2 is used for realizing additive operation, inverse amplification operation and division operation; the multiplier U3 realizes derivation operation and inverse amplification operation of the signal; the integrated operational amplifier U4 is used for realizing integral operation; the multipliers U5 and U6 are used for realizing multiplication; and the multiplier U7 multiplies the control signal by an input voltage signal to obtain the final memristor point flow. The device is used for simulating volt-ampere characteristics of the memristor and replacing an actual memristor for experiment, application and research.

Description

technical field [0001] The invention belongs to the technical field of electronic circuit design and relates to a memristor circuit model, in particular to the design and realization of an arctangent trigonometric function voltage-controlled memristor circuit model. Background technique [0002] Mr. Cai Shaotang first proposed the concept of memristor in 1971. Memristor is the fourth basic circuit element different from resistors, capacitors and inductors. Wide range of potential applications. Until 2008, Williams et al. of HP Laboratory in the United States successfully developed the first memristor device. Since then, memristor has attracted the interest and attention of many researchers, and has quickly become one of the research hotspots. Memristor increases the number of basic circuit components to four, which provides a new research space for circuit design and application, and has important application value in chaotic oscillator circuits, image encryption, artificia...
