- Abstract
Portable/implantable multimedia tools have become increasingly popular in recent years, and data transfer's security is so important in models of these tools. To ensure data's stable transfer, a robust voltage regulator is required. Meanwhile, this data transfer usually requires relative complex voltage supplies from limited voltage sources. These specific voltage supplies, which are usually higher than the battery's output voltage, are widely used by multimedia tools to accomplish interactive communication with the human body. This paper describes a novel regulator design to generate higher voltages from a lower voltage supply (e.g. battery's voltage), and the robustness of this regulator could ensure data transfer's security in multimedia models. We first designed a reconfigurable output voltage for compatibility with different multimedia applications. The regulator was made to be highly efficient, fulfilling a critical characteristic for portable/implantable multimedia models. This design also demonstrated reliability and robustness, allowing the highest output voltage to approach to the process tolerance. From simulation, it was indicated that the regulator design had better electrical parameters and more robustness than previous studies, which could ensure the data security for multimedia models.
