Zero voltage switching multi resonant converter using 0.6µm technology

Technology used for high performance DC-DC voltage regulator based Integrated Circuits is evolving. Zero voltage switching buck converter is one such DC-DC regulation schemes integrated in the power conversion circuitry and is designed such that power density is maximized and the switching losses are reduced. This paper discusses the design of AMI06 technology based zero voltage switching buck converter operating at 1 MHz switching frequency. A design example accommodating input voltage range from 5V–8V DC at a constant DC output voltage of 3V was considered. The simulations were performed on Cadence tool to verify the feasibility of the proposed converter. Finally this zero voltage switching buck converter is compared to the conventional buck converter in terms of switching losses and efficiency.
