Teaser
- Is the maximum DNL for the DAC likely to occur at a particular code? If yes, what is that code? Provide your answer for each case - binary architecture as well as thermometric.
- Calculate AIBANK,BIN⁄AIBANK,THERM for a 10-bit DAC if you were to meet the same DNL Max specification with both these architectures. AIBANK,BIN is the total area of the current-source bank in the binary architecture & AIBANK,THERM is that of the thermometric.
The winner for Teaser is Ajmal V K from NIT, Calicut. Congratulations Ajmal.!!

Assuming that the only source of DNL in a DAC is random mismatch between current sources (read below for the background),
