Multi-stage noise band cancellation SD Modulator for digitisation of distorded signal

Abstract :

A new sigma-delta modulator (SDM) architecture is proposed to digitise wideband distorted signals. It combines frequency band decomposition with bandpass (BP) SD converters and cascaded architectures. The novelties are the use of the residual signal transfer function at the output of the first summing node in a classical BP SD that is an almost free signal shaping in the SDM and the digitisation of the shaped noise in order to cancel it out in a particular band.
