Multiple-Signal Single-Loop Filter (MSSF) sigma-delta modulators

This paper presents a new family of Sigma-Delta modulators, the so called Multiple-Signal Single-Loop Filter (MSSF) modulators, where several input signals are added at the modulator input, then passed through only one single loop filter, and converted to digital by means of a column of quantizers,...
