“…The Chua's diode, or NR, a vital component of a Chua's circuit, has undergone extensive modifications for smoother linearity and cubic linearity [ 11 ]. Chua's diode using various ABBs is well documented in the literature by using Current Conveyor [ 12 ], Current-Controlled Current Conveyor Feedback Amplifier (CCCFA) [ 13 ], Current Differential Transconductance Amplifier (CDTA) [ 14 ], Extra-X Current Controlled Current Conveyor (EXCCCII) [ 15 ], Current Controlled Current Conveyor Transconductance Amplifier (CCCCTA) [ 16 ], Voltage Differencing Transconductance Amplifier (VDTA) [ 17 ], Voltage-Differencing Gain Amplifier (VDGA) [ 18 ], and many others. Other feasible alternatives may be the use of a voltage-mode operational amplifier in the Chua circuit, which limits the performance in terms of frequency and linearity [ [19] , [20] , [21] ].…”

“…Therefore, while numerical simulations provide valuable insights, their theoretical guidance may be limited. However, thanks to the rapid advancements in nonlinear circuits, mechatronics, and other related fields, a novel approach to validating the results of numerical analysis experiments has been developed [ 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ], namely, equivalent circuit experiments. Marcondes et al successfully validated the numerical analysis outcomes by constructing the equivalent circuit of the Watt centrifugal regulator system [ 31 ].…”

Alterations in the dynamical properties of an atomic force microscope microcantilever beam system in tapping mode can appreciably impact its measurement precision. Understanding the influence mechanism of dynamic parameter changes on the system’s motion characteristics is vital to improve the accuracy of the atomic force microscope in tapping mode (AFM-TM). In this study, we categorize the mathematical model of the AFM-TM microcantilever beam system into systems 1 and 2 based on actual working conditions. Then, we analyze the alterations in the dynamic properties of both systems due to external excitation variations using bifurcation diagrams, phase trajectories, Lyapunov indices, and attraction domains. The numerical simulation results show that when the dimensionless external excitation g < 0.183, the motion state of system 2 is period 1. When g < 0.9, the motion state of system 1 is period 1 motion. Finally, we develop the equivalent circuit model of the AFM-TM microcantilever beam and perform related software simulations, along with practical circuit experiments. Our experimental results indicate that the constructed equivalent circuit can effectively analyze the dynamic characteristics of the AFM-TM microcantilever beam system in the presence of complex external environmental factors. It is observed that the practical circuit simulation attenuates high-frequency signals, resulting in a 31.4% reduction in excitation amplitude compared to numerical simulation results. This provides an essential theoretical foundation for selecting external excitation parameters for AFM-TM cantilever beams and offers a novel method for analyzing the dynamics of micro- and nanomechanical systems, as well as other nonlinear systems.

“…Therefore, it is not necessary to design a circuit to balance the gain and bandwidth as a voltage feedback amplifier [15][16][17]. Therefore, using CFOA to realize chaotic circuits has become a hotspot because CFOA has better frequency gain characteristics [18][19][20][21][22][23][24]. It makes the circuit structure simpler and more flexible due to its good port characteristics [25][26][27][28][29].…”

A novel, simple Jerk chaotic circuit with three current feedback operational amplifiers included (CFOA-JCC) is proposed, which has a simpler circuit structure, fewer components, but higher frequency characteristics. The dynamic behaviors of CFOA-JCC are analyzed, including equilibrium, stability, Lyapunov exponent, bifurcation diagram, offset boosting, and phase diagram. Furthermore, the frequency spectrum characteristic of the ordinary op-amps Jerk chaotic circuit was compared with CFOA-JCC under the same circuit parameters, and the chaotic attractor frequency of CFOA-JCC can reach about 650 kHz, much better than that of ordinary op-amps (12 kHz). Numerical simulation shows that CFOA-JCC has coexisting attractors, verified by hardware circuit experiments.
