Abstract
A digital controller comprises two control paths each having an A/D converter. One of the two converters has a substantially higher sampling speed and lower resolution than the other. Thus, one is suitable to deal with the fast responses while the other is suitable to deal with the slow responses, and can replace high-speed high-resolution A/D converter which is high in both cost and power consumption.
