To improve the integration and sensitivity of surface plasmonic resonance (SPR) detection systems, we have numerically inversigate the SPR microfluidic integrated side polished fiber (SPF) sensor to detect the biological analytes. The proposed device consists of PDMS microfluidic channel and few layer MoS2 nano coated SPF. Finally, the integrated microfluidic channel with SPF bio sensor evaluated ...Show More
Nanomaterial Coated Side Polished Fiber for Early Diagnosis of Cardiovascular Disease by Label-free Sensing of Troponin Biomarker
M. Valliammai;J. Mohanraj;Balasubramanian Esakki;Lung-Jieh Yang;Chua-Chin Wang;T. Sridarshini
2023 IEEE Workshop on Recent Advances in Photonics (WRAP)
Year: 2023 | Conference Paper |
In this paper, we report a high sensitive biosensor to prognosis of CVD. Further, Troponins is identified as diagnostic biomarker to detect the early diagnonis of CVD. We have proposed a high sensitive and label-free lossy mode resonance (LMR) based biosensor. To the best of authors' knowledge, this is the first report on fiber optic biosensor for detecting Troponins T (cTnT). Besides, the propose...Show More
Three-level DC-DC Buck Converter Architecture Using Digital Pulse Width Modulation
Jyoshnavi Akiri;Venkata Naveen Kolakaluri;Lung-Jieh Yangt;Balasubramanian Esakki;Ponnan Suresh;Chua-Chin Wang
2023 IEEE Symposium on Industrial Electronics & Applications (ISIEA)
Year: 2023 | Conference Paper |
This study demonstrates a high efficiency 3-level DC-DC buck converter using DPWM (digital pulse width modulation). It is mainly featured with the replacement of traditional flying capacitor with a capacitive voltage divider, which will constantly maintain the half of the supply input voltage. Consequently, one of the power MOSFETs in the output stage will be removed to reduce conversion loss. The...Show More
A 500-MHz 32-bit DETFF-based Shift Register Utilizing 40-nm CMOS Technology
Jyoshnavi Akiri;Lean Karlo Santos Tolentino;Lung-Jieh Yang;Balasubramanian Esakki;Sivaperumal Sampath;Chua-Chin Wang
2022 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)
Year: 2022 | Conference Paper |
Cited by: Papers (1)
A double-edge triggered flip-flop (DETFF) has the distinct ability to latch data at either the rising or the falling edge of the edge unlike the single-edge triggered flip-flop (SETFF). The proposed DETFF uses parallel dual paths that work without the need of keepers for input signal boost and an inverting clock for the opposite phase operation. A Schmitt trigger replaced the conventional feedback...Show More
A Low-Energy 8-bit CLA Realized by Single-Phase ANT Logic
Durga Srikanth Kamarajugadda;Oliver Lexter July A. Jose;Lung-Jieh Yang;Balasubramanian Esakki;Sivaperumal Sampath;Chua-Chin Wang
2022 International Conference on IC Design and Technology (ICICDT)
Year: 2022 | Conference Paper |
Cited by: Papers (1)
Low power and high-speed carry look-ahead adder (CLA) is one of the most demanded digital computation units. This paper demonstrates a CLA based on single-phase ANT logic to achieve low power and high speed. It is featured with load capacitance reduction and no internal loop to enhance the speed and reduce switching activity at the same time. The proposed design is proved to work at the clock freq...Show More
A new vortex-based device using dragonfly wing to reduce the chip size
Pang-Lun Wang;Jhih-Syuan Ciou;Lung-Jieh Yang;Yung-Chiang Chung;Niroj Kapri;Balasubramanian Esakki
2017 IEEE 12th International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)
Year: 2017 | Conference Paper |

This work presents a new vortex-based flow device. A corrugated dragonfly wing blocks in a microchannel of 250 μm wide good to capture particles and to reduce the chip size. Two conclusions have been found. The new flow chips made of PDMS and their microbes filling experiments firstly revealed that only one dragonfly wing in the channel works in particle capture but without choking. Secondly, COMS...Show More
Dynamics and control of collaborative robot manipulators
2015 International Conference on Smart Technologies and Management for Computing, Communication, Controls, Energy and Materials (ICSTM)
Year: 2015 | Conference Paper |
Cited by: Papers (3)
The kinematics and dynamic relations of manipulators as well as the object are studied. The combined dynamics of the system is obtained with the help of coalescing the dynamics of manipulators and the object. In order to avoid the complex calculations of regressor, a robust adaptive control (RDC) law is formulated. The benefits of designed controller: the control law is given with the help of simp...Show More
Vision based algorithms for MAV navigation
2015 IEEE International Conference on Electrical, Computer and Communication Technologies (ICECCT)
