Mostly the reduction of power dissipation work is concentrated on switching and leakage current. However, sub threshold current is also a big factor which leads to power consumption especially for memories. In this paper, leakage power of SRAM memory cell is reduced by power gated sleepy stack structure which leads to lesser power dissipation. The power dissipation is reduced to 226 µW with proposed technique compared with power dissipation of conventional 6T SRAM cell which had 740 µW. With lesser power dissipation the circuit can have more battery backup and lesser heat emission

Microstrip patch antenna (MPA) is very easy to build and has low production cost which makes it a very good choice in large number of applications. These applications include wireless LAN, mobile satellite communication, and global system for mobile communication, missile, and so on. All these applications owe to certain advantages of microstrip patch antenna such as low profile, low cost, low mass, and very easy to integrate. The resonance of these antennas can be achieved at any frequency by varying various antenna parameters and shape of the patch. The antennas having different shapes of patches have been discussed in this paper. As the technology is growing at a very fast rate, the application of antenna in various fields plays a very crucial role. The antenna has widespread types, and each type has a particular type of application. Power consumption is reduced with the use of microstrip patch antenna. The specific IoT application defines the design and choice of antenna which depends upon various frequency bands and the transmission strength. The paper highlights various antennas which are used very frequently in the applications of IoT along with their frequency bands.

Detection using point feature method is much effective technique to detect a specific target instead of other objects or within clutter scene in an image. It is done by comparing correspondence points and analyzing between cluttered scene image and a target object in image. This paper presents novel SURF algorithm that is used for extracting, describing, and matching objects in colored images. The algorithm works on finding correspondence points between a target and reference images and detecting a particular object. Speeded-up robust features (SURF) algorithm is used in this study which can detect objects for unique feature matches and which has non-repeating patterns. This approach of detection can robustly find specified objects between colored cluttered images and provide constriction to other achieving near real-time performance.

Radio frequency-based Micro-Electro-Mechanical System (RF-MEMS)-based devices can enable various front end functions, non-reciprocity, filtering, radiation and equalization with small size, weight and better performance for IoT and 5G applications.. RF-MEMS based devices have widely grown over the last two decades due to their low power consumption, low loss and superior performances. RF-MEMS switch is mostly used for signal processing functions in microwave and RF circuits. In this paper, a switch is designed with a square plate of polysilicon with silicon nitride as dielectric. A DC voltage is applied to the design, which is greater than pull in voltage across the structure of switch. Penalty-based contact force is applied to the design, which makes the bridge comes in contact with dielectric. The structure showed spatial dependence on total displacement. The capacitance increased by a factor of 55 approximately.

Due to lack of light or less shutter speed the image becomes blurry and causes significant degradation in image. The information in the image is affected by this effect. In digital imaging recovering the unbluured color image from these images is fundamental research problem. There are various types of blur like motion blur, Gaussian blur etc. Various techniques have been introduced to deblur the images, but specific method is used to deblur specific type of blurring. In this paper, approach is used to deblur the images when we do not have any information about the type of blur. The algorithm is based on blind deconvolution and is used to deblur color image. Algorithm uses damped Richardson-lucy algorithm for each iteration. The algorithm computes blurred image and restores using point spread function (PSF).

Infrared technology has replaced the radar-guided missiles. The missile guidance system based on infrared technology or the IIR seekers does not provide any indication that they are tracking the missile and therefore called as passive devices. It has become very necessary to study the defense strategy related to Infrared technology. The effectiveness of the overall missile system is determined by the individual components and the key parameters that describe them. The design equations corresponding to the efficiency of different components used in the substems are discussed. The IIR seeker is a very critical element used in the guidance system of the missiles. Many disciplines related to the IIR missile such as signal processing, optics, microelectronics, manufacturing, and stabilization are integrated together and are discussed in the paper.

For solid-state lighting, thermal management is a very critical factor to enhance the device’s performance. In the Flip Chip Light Emitting Diode (LED), the active region is the main source of heat generation. This heat is to be conducted through different layers to the heat sink. The adhesive layer and bump assembly cause heat dissipation because of their low conductivity values and poor transparency and hence cause degradation in performance of FC-LEDs. In this paper, thermal analysis of flip chip LED is done to find out how material, size of die and bumps affect the thermal performance of FC-LED. A flip chip LED structure is modeled on a GaN substrate. Different material properties of silicon, gold, and aluminum have been studied to perform the thermal analysis and to see the effects of different die sizes, bump sizes, and adhesive materials. Thermal analysis of the high-power FC LED by using the Finite Element Method is done on Ansys Software. The FC structure and its meshing design are presented.Temperature variation with different sizes of bump, chip-die and different adhesives (silver filled epoxy, Au-Sn, Pb-Sn) on flip chip LED is discussed. The result shows that thermal heat is directly proportional to the size of the bump and the type of adhesive material selected also affects the performance of FC-LEDto some extent.
