Design methodology for low-power, low-voltage inductor-less Chua's chaotic oscillator Chandan Kumar Choubey, Amit Gupta, Aruna Pathak Methodsx, 2025 This paper describes the design and modeling of a low-power, low-voltage Chua's chaotic oscillator using Dynamic Threshold Metal Oxide Semiconductor (DTMOS) technology. The primary active block used for this design is the DTMOS-based Dual-X Second-Generation Current Conveyor (DXCCII), which is an efficient current-mode active block that dramatically improves circuit performance and efficiency. The nonlinear active element of the Chua circuit, also called the Chua diode, is built using a single DXCCII block. Also, a synthetic inductor using only one DXCCII is used instead of a real inductor is used, which eases the fabrication process. As a result, the complete circuit requires only two DXCCIIs, allowing for an inductor-free design. The suggested circuits, including the Chua diode and Chua circuits, are simulated in PSPICE utilizing TSMC 180 nm CMOS technology. A DTMOS implementation of the DXCCII has been realized and utilized in the simulation with 180 nm CMOS technology. The slopes and the breakpoints of the nonlinear resistors are obtained from the V-I characteristics of Chua's diode, which confirms the theoretical and mathematical predictions. Attractors and chaotic waveforms obtained in the simulation validate the proposed DTMOS-based Chua chaotic oscillator. The circuit uses a bias voltage of ±0.2 V and consumes only 1.58 µW.•A low-power, low-voltage design of Chua's chaotic oscillator using DTMOS technology has been proposed in this paper.•With only two DTMOS-based DXCCIIs, an inductor-less design has been implemented.•The proposed circuit uses a bias voltage of ±0.2 V and consumes only 1.58 µW.
Enhanced Parkinson's Disease Diagnosis: A Machine Learning Approach with RSCV and ADASYN Isha Verma, Rohit Agrawal, Chandan Kumar Choubey, Ranjeet Kumar Singh Proceedings of the 2025 International Conference on Artificial Intelligence and Emerging Technology Global AI Summit 2025, 2025 A degenerative neurological ailment that affects the nervous system and the body’s nerve-controlled areas is termed Parkinson’s disease (PD), causing motor and cognitive symptoms that can resemble other conditions. Many machine learning techniques have been proposed in the literature for PD, however, these have limited performance. In this paper, we seek to determine PD using multiple ML models, such as Random Forest, Support Vector Classifier, etc.. However, Using these models in the standard form does not enhance the performance. Hence, in this paper, to enhance the models’ performance, we perform hyperparameter tuning based on RandomizedSearchCV (RSCV), and ADASYN (Adaptive Synthetic Sampling).We perform experiments on a dataset, extracted from the machine learning repository at the University of California, Irvine (UCI), including 195 voice recordings of "31 patients" exams. We experimentally show that combining RandomizedSearchCV and ADASYN with standard methods (KNN, SVC, and RF, etc,) improves the performance as compared to the existing approaches. We obtain the highest scores across all metrics when using RSCV with SVC, showing significant improvement with hyperparameter tuning. Here, we achieved a 97% average accuracy, a 86% average recall, a 100% average precision, and a 93% F1-score.

A method to design a fast chaotic oscillator using CCTA Chandan Kumar Choubey, Aruna Pathak, Manoj Kumar Tiwari Methodsx, 2024 This article introduces a novel method for designing a fast chaotic oscillator using a CCTA (Current Conveyor Transconductance Amplifier) based on Chua's circuit. The proposed method uses innovative configurations and advanced simulation techniques to overcome challenges in high-speed operation, nonlinear dynamics, and Analog Building Block (ABB) selection. The design begins with nonlinear negative resistance, essential for Chua's diode characteristics, including two negative resistances, NR1 and NR2. The circuit integrates one CCTA block, two grounded capacitors, two fixed resistors, one inductor, and one potentiometer. It is simulated using PSPICE with IC (Integrated Circuit) macro-models and 180nm CMOS (Complementary Metal Oxide Semiconductor) technology. Various chaotic waveforms and attractors are produced, validating the theoretical and mathematical predictions. By varying the resistance values (1450Ω, 1650Ω, 1800Ω, 1950Ω), the circuit exhibits different chaotic behaviors, such as large limit cycles, double-scroll attractors, Rossler-type attractors, and I-periodic attractors. FFT (Fast Fourier Transform) analysis confirms the highest dominant operating frequency of 37.5MHz. A Monte Carlo simulation with 100 runs shows maximum voltage variations in the chaotic waveforms of 5.21 % and 4.61 % across the capacitors, demonstrating robustness and reliability. This design offers significant advancements in implementing high-frequency chaotic oscillators, with potential applications in various fields requiring chaotic signal generation.•A novel design of Chua's diode and Chua's chaotic oscillator using only one CCTA block is presented in this paper.•The proposed chaotic oscillator achieves the highest operating frequency of 37.5MHz.•The proposed circuit is simulated using commercially available ICs (MAX435 and AD844) and CMOS 180nm technology in PSPICE to confirm its workability.
Design method for VDCC-based analog comb filter for power line interference cancellation Chandan Kumar Choubey, Sumit Kumar, Sanjeev Kumar Pippal Methodsx, 2024 An analog comb filter is implemented by linking multiple VDCC-based notch filters in a cascading fashion (N in total), eliminating N different pole frequencies. This study focuses on suppressing a fundamental frequency of power-line interference of 50 Hz and its consecutive three odd harmonics at 150 Hz, 250 Hz, and 350 Hz. One significant advantage of this comb filter is the independent control over filters' parameters like quality factor and pole frequency. Additionally, these filters can be electronically tuned by adjusting the transconductance gain of VDCC. The suggested notch filter configuration involves 2 capacitors, 2 resistors, and 1 VDCC element. Extensive simulations were conducted using PSPICE simulator software to validate the effectiveness of these filters. The basic building block, VDCC, is designed and implemented in the simulation using integrated circuits MAX435 and AD844.•Design uses a VDCC-based high Q notch filter as the active building block.•The filter employs fewer active and passive components.•Simulated results using commercially available ICs, MAX435 and AD844, confirm the filter's practical utility.

Enhancing Parking Efficiency and Mobility with IR-based Smart Parking Management System Priyanka Gupta, Navani Pendse, Chandan Kumar Choubey 2024 8th International Conference on Computing Communication Control and Automation Iccubea 2024, 2024 Urban mobility is severely hampered by the growing trend of urbanization and the population growth of vehicles, especially regarding parking spaces in crowded, busy areas. The suggested system uses cutting-edge technology like wireless communication, data analytics, and the Internet of Things to improve parking space utilization. With a more user-friendly user interface, this strategy seeks to improve urban transportation and reduce traffic. The "Smart Parking Management System" that is being suggested uses sensor nodes that are placed strategically across parking lots to collect data in real-time about parking spaces that are available and those that are occupied. Through communication between these sensors and a microcontroller, a network is created that continuously checks and updates the status of parking spaces. Users can access this information through a Telegram bot to remotely identify and reserve available parking spaces. The system creates a sustainable and user-friendly urban environment by streamlining traffic and allocating parking spaces optimally.
