The present invention is related to a sigma-delta analog-to-digital converter (ADC). It further relates to a method for designing and manufacturing a sigma-delta ADC, and to a digital control loop comprising the same. According to the present invention, part of the filtering function required for noise-shaping is implemented in the feedback path. By suitably distributing the poles over the forward and feedback paths, stable operation can be achieved while offering low latency. |
