Abstract: A pipeline analog to digital (A/D) converter for converting an analog input signal into a digital representation of the analog signal. The pipeline A/D converter has a sample and hold stage, the sample and hold stage sampling and holding the analog input signal and outputting a sampled and held signal. The pipeline A/D converter also has a first analog signal converter stage, the first analog converter stage producing a digital output based on the sampled and held signal, from which a most significant bit of the digital representation of the analog input signal is derived. The first analog converter stage produces a residue signal based on a comparison of the analog input signal and an analog representation of the digital output.
