Network reconfiguration in a data converter for improved electrical characteristics

摘要

A process of optimizing a resistor-2 resistor (R-2R) digital-to-analog converter (DAC) by partial resistor network reconfiguration is disclosed. The method includes analyzing a circuit to determine whether any specifications are outside predetermined limits. The method further includes determining one or more addresses that cause the circuit to be outside of the predetermined limits. The method further includes defining logic to detect address information and control function to alter the circuit to improve the specifications. The method further includes installing the control function into the circuit to improve the specifications.

1. A method implemented in computing infrastructure, comprising
analyzing a circuit to determine whether any specifications are outside predetermined limits and whether one or more addresses exist that have yet to be analyzed; determining whether at least one of the one or more addresses cause the circuit to be outside of the predetermined limits; defining logic to detect address information and a control function to alter the circuit to improve the specifications; and installing, by the computing infrastructure, the control function into the circuit to improve the specifications wherein the specifications comprise integral non-linearity (INL) and differential non-linearity (DNL).
