Summary :

New cyclic switched-capacitor (SC) D/A and A/D converters are proposed. In the former, a capacitor-mismatch-compensation technique using additional small capacitors is introduced. With this, a capacitor ratio accuracy as high as twelve bits is possible. And, in the latter, the A/D conversion with ten-bit accuracy is realizable by the simple ratio-independent circuit consuming only a few number of clock cycles for each bit conversion.
