Preventing overload of a quantiser in analogue and digital converters

摘要

A signal converter comprising means for quantizing an input signal and for generating an output signal in dependence on the quantized input signal, includes a non-linear circuit in the forward signal path which receives at least two differentially delayed input signals and generates an output signal jointly responsive thereto, and a feedback path responsive to the output of the non-linear circuit to affect the signals input thereto.
