A calibration technique for very low current and compact tunable neuromorphic cells: Application to 5-bit 20nA DACs
(Institute of Electrical and Electronics Engineers, 2008)
Low current applications, like neuromorphic circuits, where operating currents can be as low as a few nanoamperes or less, suffer from huge transistor mismatches, resulting in around or less than 1-bit precisions. Recently, ...
