Abstract
A method to tune electronic devices in general using R/2R ladder networks to obtain fixed or variable accurate properties that may include, but are not limited to resistance, current, voltage, and/or timing. As a particular application, a method for internally calibrating a digital-to-analog converter is shown in detail. The DAC uses an extended R/2R ladder to improve the converting accuracy by mapping the extended bits into the original bits. A mapping matrix is maintained, which can be rewritten by an internal calibration process.
