Abstract
A device may include a sigma-delta analog-to-digital converter (ADC) configured to convert an analog input signal to a digital signal that is a digital approximation of the analog input signal. A bitstream modifier is configured to receive the digital signal, output a first signal that is based on the digital signal at a first output terminal and output a first difference signal at a second output terminal that includes a first difference value between a first value of the digital signal and a second value of the digital signal. The second value is immediately prior to the first value in the digital signal. An error correction system is configured to receive the first signal, receive the first difference signal, use the first signal and the first difference signal to determine a correction value, and modify the digital signal to generate a corrected digital signal by applying the correction value.
