Using operational transconductance amplifiers for Chua's circuit

摘要

A new approach to Chua's circuit is developed in this paper. OTAs(Operational Transconductance Amplifiers) are used to synthesize it. Firstly, OTAs are utilized for grounded inductors and piecewise-linear resistors. Then, OTAs are also used for a new variable parameter of current type Chua's circuit. Moreover, the Lyapunov exponents are calculated. Furthermore, the power spectrum and the Poincare section are given. Finally experiments results approve this approach.
