Abstract :
A novel way to obtain a very high accuracy in the bit weighting required for bipolar monolithic digital-to-analog (D/A) converters is described. The new method combines passive division using matched elements with a time division concept, needs no trimming, and is insensitive to element aging. A 12-bit monolithic D/A network with internal reference sources, built as a test circuit, demonstrates the versatility of this new technique.
