Abstract
A frequency translating analog-to-digital converter for receiving an analog band-pass signal is described. The analog-to-digital converter comprises an adder/input block for receiving the analog band-pass signal and an analog band-pass feedback signal, thereby forming an analog band-pass error signal. The analog-to-digital converter has at least one analog mixer for mixing and down converting the analog band-pass error signal and thus generating a down-converted analog error signal and at least one quantization path for generating at least one digital signal. The quantization path is adapted to be fed with the down-converted analog error signal and to output the at least one digital signal, and comprises at least one of an inner feedback path for feeding back the at least one digital signal to the at least one filter element or a feed forward path for feeding forward the down-converted analog error signal feeding to the at least one filter element, wherein the inner feedback path comprises an inner digital-to-analog converter. An outer common feedback path is provided for feeding the at least one digital signal back to the adder block, the outer feedback path comprising a digital-to-analog converter, to convert the at least one digital signal into an analog band-pass feedback signal.
