摘要：
A reduced chop rate analog to digital converter technique including selectively weighting input samples to a digital filter, alternately inverting the polarity of an input error into positive and negative error components; and generating the positive and negative error components in a plurality of time response intervals of the digital filter in which the sum of the weights of the positive and negative error components are substantially equal.
