Abstract
A double-input oversampling modulator (DIOM) is proposed for analog/digital converter design. The main property of the method is that it allows arbitrary noise shaping functions, provided that stability is assumed. Finite zeros can be introduced. For bandpass type input signal a DIOM can be designed with a much lower sampling rate than a sigma-delta modulator. The requirement on op amp settling time can thus be greatly reduced. Sensitivity behavior of DIOMs is discussed and a multistage design example is provided.
