ith temperature and time in order to operate properly. In a battery operated system the battery voltage is not stable, e.g. it decreases with decreasing temperature and with ageing. In that case a voltage regulator must be used, that regulates the battery voltage and generates a stable supply voltage to power other circuitry. In this thesis a voltage regulator to be used in a battery operated system has been designed which meets the given specification of stability and power capabilities. A voltage reference, which is a commonly used devise in analog circuits, was also designed. The role of a ..................[:=> Show Contents <=:]

tant voltage level within limits set by the electric utility. All the distribution stations have a Single-phase voltage regulators which is very important for providing
reliable power to the customers. the range of loading conditions tends to change the transmission voltage level which is then adjusted by the voltage regulators by increasing or decreasing the difference in the voltage level from
the transformer to the distribution circuits. A maximum of 10% voltage variation in intervals (steps) from the neutral level is provided by most of the transformers. power quality problems, potenti..................[:=> Show Contents <=:]

tical use of the lossless DCR inductor current-sense technique for a high-current high frequency application.
Also repeated the analysis for low current high-frequency dc/dc converters operating in CCM and DCM.
Implemented and explained in detail each stage of the sense process in order to recover correctly an accurate equivalent voltage image of the inductor current.
Experimental tests employing VRMs have been completed by demonstrating higher performances of the DCR current sense technique compared with Rshunt sense one.
