Abstract

In this paper a new structure for a band-pass sigma delta modulator is proposed. The center frequency of the modulator can be tuned in the range between DC to half the sampling frequency by means of only one parameter. The modulator stability and the nearly constant resolution for the whole frequency range are demonstrated.
