Novel fourth-order sigma–delta convertor

Abstract
A new fourth-order sigma–delta A/D convertor is proposed as a cascade of two second-order sections. Its advantages over the alternative cascade of four first-order sections are presented. It is also shown that the proposed design gives certain improvements in performance over a third order cascade of a second and first-order section, thus justifying the use of a higher order.
