Abstract :
In the original paper (see IEEE J. Solid-State Circuits, vol. 27, p. 1679-88, 1992) a gain-proration technique is introduced to correct the interstage gain error that occurs when multiple stages of a multistep analog-to-digital converter are calibrated. In this brief, however, it is shown that correction of this interstage gain error is unnecessary for multistage analog-to-digital converter self-calibration.
