ABSTRACT:
The present invention provides a technique for improving the resolution of an A/D converter. The input analog signal is sampled to generate an analog level and the analog level is held for an interval. A random noise signal having zero average value is superimposed on the held level to generate a fluctuating voltage. This fluctuating voltage is then sampled a plurality of at least N times, and N sampled values are communicated to the A/D converter so that N digitized values are generated. These digitized values are averaged to provide an output having a digitization error reduced by a factor of N.sup.1/2.
