Abstract

A high performance voltage down converter (VDC) is proposed in this paper. The proposed VDC can automatically control the driving current in seven phases to reduce the fluctuation of output voltage in VDC. By using above new flexible control technology of driving current, the fluctuation of output voltage can be suppressed to less than 10% and the average consuming current of VDC can be suppressed to 34 μA, even if the operation frequency is 200 MHz at the average driving current 100 mA. Therefore, the proposed VDC can operate with large driving current, low-power consumption and good response at the same time. Above all, this technology is very suitable for high perform ULSIs which require large load current, very low-power and high speed operation.
