Abstract :
A versatile two-phase-monolithic voltage regulator (MVR) chip has been developed and fabricated using traditional 0.5micron CMOS technology. The chip is designed to work at up to 4Mhz and 5V to 1V power conversion with good efficiency. In this paper, the author will discuss some major design issues of this MVR chip, including the benefits and limitations of the sub micron CMOS technology in this kind of all in one power conversion application.
