Abstract

The invention relates to a negative resistance equivalence method for Chua's chaotic circuits. The method includes: utilizing negative differential resistance (NDR) characteristics of a hybrid structure device (SETMOS (single electron transistor metal oxide semiconductor)) of an SET and an MOS to realize a nonlinear function of a chaotic circuit, and applying the nonlinear function to a Chua's circuit to replace negative resistance. Stimulation of the circuit shows that the method is effective, the circuit is easy to realize, output signals have wide dynamic range, and the method is expected to have wide application prospect and important application value in fields of radar, secret communication, electronic countermeasure and the like.

Description

technical field [0001] The invention relates to a negative resistance equivalent method of Chua's chaotic circuit, which belongs to the technical field of electronics and communication. Background technique [0002] In recent years, chaotic circuits have been widely used in communication and control fields and many other fields due to their extreme sensitivity to the initial state and control parameters, as well as complex characteristics such as wide frequency spectrum and randomness. in-depth and extensive research. Chua's circuit is a typical chaotic signal generation circuit. There are many studies on this circuit. As we all know, with the development of VLSI, the device size has entered the nanometer level. It is an inevitable trend for new devices to replace traditional devices to realize circuits. However, based on Single-electron transistor (SET) and metal-oxide-semiconductor (MOS) hybrid device SETMOS have negative differential resistance NDR characteristics to rea...
