Abstract

This paper describes the evaluation of the Voltage E)own Converter (VDC) with low ratio of consuming current to load current in DC/AC operation mode. The stability, response and power consumption are investigated. First, for the stability and response, the VDC can operate in the condition that the bounce of the down voltage (dVDi.) is no more than 10% of the setting voltage and the maximum load operation frequency (/max) is 100 MHz at the average load current 70mA (the maximum load current 140mA). Secondly, for the power consumption, by using this VDC technology, the value of Id IL can be suppressed to 5.1E-4 (Ic: total consuming current in VDC, IL: average load current) in the condition that dVDL is no more than 10% of the setting voltage and fmax is 10 MHz at the average load current 70 mA. Thus, it is made clear that the VDC can realize high stability, good response and low power consumption at the same time. This technology is suitable for high performance ULSIs which require large load current and lowpower consumption.
