Abstract:
Examples of a system and method for sigma-delta analog-to-digital conversion of an electrical input signal are disclosed. An electrical input signal is received. A filtered analog signal is provided based on the electrical input signal and an analog feedback signal. A digital representation of the filtered analog signal is provided, the digital representation being one of K quantization levels, wherein K is a positive integer between 2L and 2L+1, L being a positive integer. The analog feedback signal is obtained based on the digital representation.
