Abstract
A delta sigma converter according to the present invention replaces the quantizer of a conventional delta sigma converter, such as a comparator followed by a latch, with N quantizers, each operating at a reduced frequency f.sub.s /N and phase offset from each other by 2.pi./N. The quantized outputs are assembled in accordance with a control signal to produce a feedback signal at a frequency f.sub.s and the feedback signal is applied to a subtractor of the delta sigma converter.
