Abstract
Designing converters with unit elements, then the matching accuracy between the elements as a function of the number of bits is known. A 10-bit converter for example needs for lσ yield and ±½ LSB INL an element matching of 2.5%. In case we want to increase the yield to 3σ then the matching must be increased to 1.25%. In this section matching parameters of devices in MOS technology will be given. It must be noted, however, that mostly the matching parameters depend on the technology used and can differ from one supplier to the other. Furthermore these parameters are company confidential. The numbers given here are only an indication of what can be expected in a real technology. No guarantee is given about the exact values!
