Abstract
A digital communication device having a dual conversion architecture. A first rf-mixing stage is provided followed by a second, quadrature, mixing stage of which output signals are sampled by means of an analog-to-digital converter and supplied to a digital signal processor (DSP) for further baseband processing. The A/D converter is a modified sigma delta analog-to-digital converter. A mixing function is added to the A/D-conversion function by modifying the input stage of a conventional sigma delta bitstream A/D converter. The result is a reduced number of IC-external components and a reduced power consumption.
