“…The rectifier design presented in [6,7,17] does not require any passive elements for their circuit implementation. Moreover, recent articles in the literature [19][20][21][22][23][24] address the design of the rectifier, but do not provide tunability features. In [25], the current mode precision rectifier design is presented using EXCCII, but the circuit does not provide tunability features.…”

This work presents a voltage mode scheme of a full-wave precision rectifier circuit using an analog building block differential voltage current conveyor transconductance amplifier (DVCCTA) including five NMOS transistors. The proposed design is essentially suited for low voltage and high-frequency input signals. The operation of the proposed rectifier design depends upon the region of operation of NMOS transistors. The output waveform of the presented rectifier design can be made electronically tunable by controlling the bias voltage. The functional correctness and verification of the presented design are performed using 0.25-µm TSMC technology under the supply voltage of ±1.5 V. The absence of a resistor leads to a minimal parasitic effect. To obtain further insight on the robustness of the circuit, a Monte Carlo simulation and corner analysis are also presented. The circuit is verified experimentally by incorporating a breadboard model with the help of commercially available ICs CA3080 (operational transconductance amplifier) and AD844AN (current feedback operational amplifier) and offers remarkable compliance with both theoretical and simulation outcomes. The presented design has been laid out on Cadence virtuoso, which consumes a chip area of 9044 µm2.

“…Even so, there are some disadvantages, such as low adjustability, weight, large area, and high cost [82]. erefore, in order to overcome these difficulties, inductance simulators are used as substitutes for spiral inductors in many circuit applications [97]. In this study, a lossless grounded active inductor based on CCII developed by Yang is used [81].…”

In this paper, a multistable modified fourth-order autonomous Chua’s chaotic system is investigated. In addition to the dynamic characteristics of the third-order Chua’s chaotic system itself, what interests us is that this modified fourth-order autonomous Chua’s chaotic system has five different types of coexisting attractors: double-scroll, single band chaotic attractor, period-4 limit cycle, period-2 limit cycle, and period-1 limit cycle. Then, an inductorless modified fourth-order autonomous Chua’s chaotic circuit is proposed. The active elements as well as the synthetic inductor employed in this circuit are designed using second-generation current conveyors (CCIIs). The reason for using CCIIs is that they have high conversion rate and operation speed, which enable the circuit to work at a higher frequency range. The Multisim simulations confirm the theoretical estimates of the performance of the proposed circuit. Finally, using RK-4 numerical algorithm of VHDL 32-bit IQ-Math floating-point number format, the inductorless modified fourth-order autonomous Chua’s chaotic system is implemented on FPGA for the development of embedded engineering applications based on chaos. The system is simulated and synthesized on Virtex-6 FPGA chip. The maximum operating frequency of modified Chua’s chaotic oscillator based on FPGA is 180.180 MHz. This study demonstrates that the hardware-based multistable modified fourth-order autonomous Chua’s chaotic system is a very good source of entropy and can be applied to various embedded systems based on chaos, including secure communication, cryptography, and random number generator.

“…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.
