This paper presents a brief on the implementation of reconfigurable shared LUT (look-up-table) based Distributed Arithmetic (DA) for the higher order finite-impulse response (FIR) filters whose filter coefficients can be changed during run time. In this architecture all the multipliers and adders are replaced by the register banks, multiplexers and the shifters. The throughput rate of the design is...
Biometric technologies are the automated procedures for validating and identifying the originality of an individual. The biometric systems for automatic authentication are fingerprint, iris, retina, voice, hand geometry recognition. Nowadays, the retina recognition has received an importance, as the unique characteristics of the retina. In the acquisition method, the retinal images might experience...
Electronic Control Unit is an electronic system which controls different engine parameters for optimized performance. In SI engine, ECU controls the Injector opening timing and spark timing at different engine speed and load.

Multi-junction solar cells based on III-V materials are widely utilized for space applications owing to their light weight and very high efficiency. When used for terrestrial applications, they are used in concentrator systems to boost the efficiency and reduce the effective solar cell area to enhance the performance-to-cost ratio. However, the efficiency drops as the light intensity goes beyond a...

A novel trans conductance boosting technique is introduced without having any additional power consumption. A simple technique of biasing the opamp has been introduced for very low offset and without having any requirement for external reference circuit. A prototype of two stage amplifier...
Due to the technology scaling the critical charge stored in active nodes is reducing very drastically, so even very small amount of radiation charge could able to disturb the values stored in the active node. In this paper, we have proposed soft-error tolerant flip flop design. The proposed flip-flop utilizes a cross-coupled inverter on the critical path in the master-stage and generates the required...

IoT is a revolutionary technology that represents the future of computing and communications. Most of the people over all worlds depend on agriculture. Because of this reason smart IT technologies are needed to migrate with traditional agriculture methods. Using modern technologies can control the cost, maintenance and monitoring performance. Satellite and aerial imagery play a vital role in modern...
For C band receptor applications, an efficient and compact sized four port directional coupler has been designed using Substrate Integrated Waveguide technique. Dielectric filled waveguide (DFW) devices replace the microstrip devices as they are inefficient at high frequencies. With the help of via holes, DFW is converted to Substrate Integrated Waveguide (SIW) to considerably reduce the dielectric...
This paper presents the circuit simulator for noise analysis of switched-capacitor (SC) circuits using adjoint network approach in python environment. Adjoint network approach is a simpler method for noise calculations in SC circuits because just solving of the adjoint network gives the node voltages which are transfer functions (output is injected with unit current source in this approach) these...
The designed low power 10-bit 5-MS/s SAR ADC reduces the capacitor array area and switching power by 50% and 89% respectively compared to the conventional one by switching monotonically. The Capacitive digital-to-analog converter used by this ADC diminishes parasitic capacitance as special care has been taken for capacitor array formation. MOM capacitor arrays are done using common centroid placement...
