Active Low Pass Filter based Efficient DC-DC Converter .

In An efficient active filter based on-chip DC-DC voltage converter circuit is proposed which is used for application to distribute power supplies in multivoltage system. The circuit is appropriate for point-of-load voltage regulation due to an ultra area efficient architecture. Compare to other conventional voltage regulators, the proposed circuit is designed with small area and with no inductor or output capacitor. This is an alternative to classical LDO voltage regulators and hence, providing a means for distributing multiple local power supplies across an integrated circuit while maintaining high efficiency and fast response time within a small area. Thus, the performance of proposed active filter based DC-DC converter is analysed.
