ABSTRACT:
In order to reduce noise in single or multiloop analog to digital converter circuits employing n-bit quantisers (n>1), only the MSB of the quantiser output is fed back in a feedback loop in reduce problems of overload in a feed-forward (integrator filter). The feedback MSB may be subtracted as an offset from the input analog signal or used to control the sign of inversion of a signal inverter.
