In this paper, operational amplifier circuit is designed using model parameters of high-k FinFET in 22nm technology. The conventional design expressions for MOSFET based OPAMP design are fine tuned to design FinFET based OPAMP. The OPAMP design is suitable for use as sub circuit in ADC design as it supports low voltage, high speed and low power dissipation. The transistor geometries are identified so as to achieve high performance and energy efficient OPAMP. Schematic capture is carried out using Cadence tool. From the simulation studies, the designed OPAMP has a unity gain bandwidth of 100 GHz and slew rate is equal to 1V/μS. The maximum power dissipation of differential amplifier circuit is 800nW and hence suitable for all low power analog and digital circuits.

In this paper, we study the input impedance characteristics of axial mode helical antennas to find an effective way for matching it to 50 Ω. The study is done on the important matching parameters such as like wire diameter and helix to the ground plane gap. It is intended that these parameters control the matching without detrimentally affecting the radiation pattern. Using transmission line theory, a simple broadband technique is proposed, which is applicable for perfect matching of antennas with similar design parameters. We provide design curves to help to choose the proper dimensions of the matching section based on the antenna’s unmatched input impedance. Finally, using the proposed technique, a 4-turn axial mode helix is designed at 2.5 GHz center frequency and the measurement results of the manufactured antenna will be included. This parametric study gives a good insight into the input impedance characteristics of axial mode helical antennas and the proposed impedance matching approach provides a simple, useful method for matching these types of antennas.

The moth-flame optimization algorithm (MFO) is a novel metaheuristic algorithm for simulating the lateral positioning and navigation mechanism of moths in nature, and it has been successfully applied to various optimization problems. This paper segments the flame energy of MFO by introducing the energy factor from the Harris hawks optimization algorithm, and different updating methods are adopted for moths with different flame-detection abilities to enhance the exploration ability of MFO. A new energy-segmented moth-flame optimization algorithm (ESMFO) is proposed and is applied on 21 benchmark functions and an engineering design problem. The experimental results show that the ESMFO yields very promising results due to its enhanced exploration, exploitation, and convergence capabilities, as well as its effective avoidance of local optima, and achieves better performance than other the state-of-the-art metaheuristic algorithms in terms of the performance measures.

This research presents the proposed model, to control the power flow in the transmission power system by applying Unified Power Flow Controller (UPFC), STATCOM and two 3-level 48-puls converter. This hybrid has been used to improve performance and reduce the maximum over shoot which is obtained from proposed model when the fault is occurring or suddenly system changes. The behavior of the system is analyzed under different three cases. The first case, the model is applied to plus load at bus 3. The second case, the model is operating at normal work and the third case, the three phase fault is occurred at bus4. In this research, the performance of system is studied under applied all cases of the current, voltage and power for the system. The numerical results of the proposed model are introduced to show the maximum over shoot and RMS values after applied proposed control at three different cases to prove the suggested model gave a good performance especially, during three phases fault and after fault clearance.

Many methods are used to detect x-ray are incapable of accounting for the high x-ray flux generated by modern x-ray Instruments. The major technology for measurement of x-ray dose rate in real time is the ionizing chambers detectors, but it has some disadvantages like complexity. Also it has large size due to the importance of gas volume and pressure, high voltages, signal cables, and other specialized parts needed for its operation. Advances in the technology of CdTe semiconductor in solar cells industries allow the development of an inexpensive and compact solid-state X-ray sensor. As X-ray photons pass through the diode, the photoelectric effect produces a photocurrent. The X-ray flux can be determined from this current. Four stacked diodes were connected in series to measure the device performance. It was observed that amplitude of the pulse formed due to exposed FTO/CdS/CdTe/Mo detector to X-ray of 33 keV and 1mA intensity is 1.03 V

This paper sets out a new technique for designing an operational amplifier (OP-AMP) using tanner EDA 1um FDSOI CMOS Technology. Fully Depleted Silicon on Insulator used for building integrated circuits to support the temperature changes, the proposed OP-AMP operates at 3.75V power supply and 70uA bias current using the proposed Adaptive Biasing Circuitry (ABC), which its devices operate at the weak inversion to allow low power dissipation of 0.62mW. The 0.064us settling time and 37.016V/μs slew rate parameters improved by the ABC technique, reducing the power dissipation by operating the ABC devices in weak inversion. The phase margin is more than 100 degrees for the DC gain of 13.97dB, which is a reasonable margin when temperature range increases.
