Abstract
A delta-sigma analog-digital converter and method to generate a digital output signal from an analog input signal are provided. A delta-sigma analog-digital converter includes a loop input signal generating unit configured to generate a loop input signal based on both the analog input signal and a feedback signal that is based on the digital output signal, a noise shaping unit including a plurality of feedback loop stages that respectively filter fed back local error signals that are respectively based on the digital output signal, to generate a loop output signal with reduced noise over the loop input signal, and a quantizing unit configured to quantize the loop output signal and to generate the digital output signal based on the quantized loop output signal.
