By constructing the stages of a pipelined analog to digital converter (ADC) such that they are in close proximity while sharing a voltage reference, bias, and power supply, the linearity of the ADC's will match since the relatively large devices that now dictate the ADC linearity are in close proximity to one another. Supply and reference IR drops are also matched reducing gain and linearity mismatch. Based on this, it is possible to construct a shared multi-channel ADC with exceptionally good matching of gain, phase, and linearity without additional hardware to match the channels.
