9 4.5MHz, BiMOS Operational Amplifier with MOSFET Input/Bipolar Output The CA3140A and CA3140 are integrated circuit operational amplifiers that combine the advantages of high voltage PMOS transistors with high voltage bipolar transistors on a single monolithic chip. The CA3140A and CA3140 BiMOS operational amplifiers feature gate protected MOSFET (PMOS) transistors in the input circuit to provide very high input impedance, very low input current, and high speed performance. The CA3140A and CA3140

The Maximum Power Point Tracking works on the impedance matching theory. When the Thevenin impedance of the circuit (source impedance) matches with the load impedance maximum power output of a circuit is obtain. this is according to maximum power transfer theorem. Boost converter is connected to a solar panel in source side which is used in order to enhance the output voltage that can be used for different applications. Source impedance and load impedance can match by appropriately changing the duty

ABSTRACT In High Intensity Focused Ultrasound (HIFU) therapy system, electrical impedance matching networks should be used between the ultrasound transducer and signal generator in order to maximize the electrical power transmission. Impedance matching networks are designed based on LC resonant networks and that can be analyzed by analytical design theory and smith chart design technique. Graphical method using smith chart is adapted to understand the concept. The reflective power should be reduced

2.6.2 Radiation Pattern Microstrip Patch Antenna has radiation patterns that can be simply calculated. The source of the radiation of the electric field at the gap of the edge of the Microstrip element and the ground plane is main factor to the accurate calculation of the pattern for the patch antenna. Simply it can be said that the power radiated or received by the antenna is the function of angular position and radial distribution from the antenna [24]. In the fig.24 [9] below we can see the side

3.6.6 Voltage Standing Wave Ratio There should be a maximum power transfer between the transmitter and the antenna for the antenna to perform very well. This happens only when the impedance Zin is matched to the transmitter internal impedance, Zs. In the process of accomplishing this particular configuration for an antenna to perform very well, there is always a reflecting power which leads to the standing waves, which is categorized by the Voltage Standing Wave Ratio (VSWR). This is given by [30]:-

Summary The sub-system which was analyzed in the aircraft flaw detection system is the ‘sensing sub-system’. The main function of this sub-system is to determine whether the flaw detected by the scanning sub-system is valid by examining it further and notify the engineers if repair work is needed and provide them with statistics of the flaw. Movement system will then be activated so that the robot marks the points where examination has been done to ensure no repetition of inspection occurs. The

generally preferred for maximum radiation. The conducting patch can have many shape but rectangular and circular configurations are the most commonly used configuration. A microstrip antenna is characterized by its length parameter, width parameter, input impedance, and gain and radiation patterns. Various performance parameters, mathematical calculation and Microstrip feeding technique will be discussed further through this chapter. Antennas are key components of any wireless
