| Abstract: | Nonlinearity is ubiquitous in practical circuits. In this paper, a class of memristive oscillators is built based on the Sallen-Key filter and memristive diode bridge. Taking one as an example, the experimental scheme design and circuit experimental verification are completed. Results indicate that, by changing the parameters of the circuit elements, nonlinear phenomena of periodic limit cycle, quasi-periodic and chaotic oscillation can be observed. The circuit is with simple structure, convenient debugging and abundant phenomena. This experimental scheme can be used as an important research content of undergraduate course design, aiming at deepening students" understanding of the nonlinearity in circuits. |
