Averaging cell mismatches in integrated circuits

摘要

An integrated circuit may include matched cells each having an active transconductor, wherein the matched cells are coupled together through respective active transconductor circuits to average the effect of comparator input-referred offsets. Each cell of the matched cells may have a first differential gain stage coupled to a second differential gain stage that is coupled to an output buffer stage, and an associated active transconductor circuit. The active transconductor of each cell is coupled to the gain stage of other cells to average the effect of cell mismatches.
