Abstract

See full text

Disclosed is a process for minimizing digital-to-analog converter differential nonlinearity by adjusting taps in resistive elements in a fine resistor string voltage divider circuit. Active buffer circuits can be eliminated while still minimizing DAC DNL and insuring circuit monoticity.
