WebJan 1, 2012 · There are three types of CMOS offset cancellation techniques: trimming, chopping, and auto-zeroing. Trimming is usually performed during production to eliminate offset. Auto-zeroing is a sampling technique in which the offset is measured and then subtracted in subsequent clock phases. WebJun 15, 2005 · The offset of a comparator can be distinguished as systematic offset and random offset. Systematic offset can be elimated, but random offset can't. The main reason of offset is process mismatch. Of course you can increase transistor size to reduce mismatch, but the speed issue shoud be considered.
