A new incremental ADC (IADC) is proposed which extends the order of a conventional incremental ADC from N to (2 N − 1) by way of a two‐step operation. For a given conversion time, the duration of each step can be optimised. For an N th‐order IADC, the performance is equivalent to that of a (2 N − 1)‐order converter. However, it only needs the same circuitry as the N th‐order one. The new IADC is hence more accurate, and also much more power‐efficient than the conventional ones.
