“…Some authors concentrated on designing different oscillators for chaos generation. For example, chaotic behaviours of Duffing, Chua, Colpitts and Van der Pol oscillators [4][5][6][7][8][9], just to name a few, have been studied.…”

In many domains of science and technology, as the need for secured transmission of information has grown over the years, a variety of methods have been studied and devised to achieve this goal. In this paper, we present an information securing method using chaos encryption. Our proposal uses only one chaotic oscillator both for signal encryption and decryption, for avoiding the delicate synchronisation step. We carried out numerical and electronic simulations of the proposed circuit using electrocardiographic signals as input. Results obtained from both simulations were compared and exhibited a good agreement proving the suitability of our system for signal encryption and decryption.

“…For this reason, such oscillators can not have a spectrum with a flat magnitude over a wide bandwidth. This also applies to Chua's circuit which we have recently shown to have a core sinusoidal oscillator [41], [42]. Chaotic oscillators based on voltage-controlled oscillators (VCO's) which have a varying center frequency appear to be more attractive when flat spectra are required.…”

“…As shown in Fig. 2, NR can be described by a piecewise linear I-V characteristic consisting of two slopes whose limits are determined by two voltage-ranges to establish the breaking points to generate chaotic phenomenon [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. On the other hand, NR has been implemented by using operational amplifier [4], a CMOS IC design by using operational trans-conductance amplifiers (OTAs) was presented in [1], and a realization by using commercially available current feedback operational amplifiers (CFOAs) was given in [4,5].…”

The purpose of this paper is to propose a detailed analysis of the literature survey done during the design of a high frequency Chua's oscillator/chaotic oscillator using the block current conveyor trans conductance amplifier (CCTA). In literature survey, we have thoroughly studied total eight papers, that have the relevant data required for our design along with many other papers to understand the fundamental points and design parameters in order to understand the working of the circuit and noted the various methodologies and components used along with their drawbacks. In our design, we have tried to remove all the drawbacks mentioned in this paper.
