Modelling and Simulation of MPPT Boost Converter in MATLAB
Abstract: In this study we are trying to increase efficiency of solar PV plant by implementing MPPT Boost converter. In solar PV plant, input is solar incident radiation which is continuously varying. This will result in less efficient working of solar PV modules. By using maximum power point tracking algorithm implemented in boost converter, we can operate solar PV modules on their maximum power output. This will increase output of PV …

Quantum Behavior of Charge Carriers in a Symmetrical Double Gate MOSFET
Abstract: Our earlier work on modeling of single gate n-channel metal oxide semiconductor field effect transistor (MOSFET) has been extended to discuss the quantum behavior of charge carriers in symmetrical double gate (DG) MOSFET. The potential profile in the channel region of DG MOSFET has been obtained in parabolic approximation. The parabolic potential facilitates analytical expression for electric field. The appropriate Schrodinger’s equation has been solved to obtain wave functions in …

Hardware Implementation of Discrete /Inverse Discrete Cosine Transform Using Redundant Number System CORDIC Processors
Abstract: Rapid enhancement in multimedia service running on portable application has forced the development of high quality and low power implementation of complex signal processing algorithms. Image and video processing are typical application of multimedia system. Image compression and decompression using DCT/IDCT are the two algorithms commonly used in MPEG standard of image processing. For an image of N x N size, DCT/IDCT would require N4 multiplications and increases complexity. To …

Leveraging cross-coupled domino logic for low-power, two-port SRAM with resilience to Differential Power Analysis (DPA) attacks
Abstract: Side channel attacks have become a serious threat to embedded and cryptographic systems. These attacks can be deployed by capturing the power consumption traces or electromagnetic radiations from the power and communication channels. SRAM is vulnerable to such attacks. Power consumed by SRAM for various read and write operations can express the information about bits being read from or written into the bit-cells which eventually exposes the instructions and data …
