Description

technical field [0001] The invention relates to a chaotic signal generating circuit, in particular to a chaotic circuit of a fourth-order memristive bandpass filter. Background technique [0002] Due to the unique nonlinear characteristics of memristors, the research on memristive chaotic circuits with memristors has exploded in the past 30 years. Unfortunately, memristors are currently expensive and the manufacturing process is extremely complicated. Only a few companies have mastered its manufacturing technology, and they cannot be obtained from the market in the short term. Fortunately, an equivalent circuit can be designed to simulate the characteristics of a memristor using conventional analog electronics that are already available, such as operational amplifiers, capacitors, resistors, inductors, etc. When designing a circuit, considering the feasibility and practicability of the circuit, the circuit design usually aims at a simple structure and easy implementation. ...
