As devices continue the trend of becoming increasingly smaller in scale to allowfor wearability, the power supply modules driving these technologies will in turn become reduced in size as well. This progression will call for advanced techniques to fabricate power supplies on wearable device platforms which still permit the circuit to operate effectively. One such crucial technique, which is discussed in this thesis, is the implementation of power saving measures to increase battery lifespan on wearable devices.

Equipment found in the medical field today can be quite bulky and requireinconvenient means of transportation and take up an excessive amount of space. Thus, the medical industry is booming with a demand for wearable small scale devices to be used as medical diagnostic equipment. This study takes a closer look at the development of a power supply design for a wearable medical diagnostic device. This apparatus utilizes Speckle-plethysmography to effectively analyze the cardiovascular health of the patient, and therefore must utilize a relatively noise-free and battery operated power supply to function properly.
