==Digital-to-analog converter and method for amplitude and skew error correction in the digital-to-analog converter - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240213992 titled 'Digital-to-analog converter and method for amplitude and skew error correction in the digital-to-analog converter

==Simplified Explanation==
This patent application describes a method for correcting errors in a digital-to-analog converter (DAC) by using a correction DAC to adjust the output of the main DAC based on error data.

* The DAC includes a main DAC with multiple cells, a cell error determination circuit, a correction DAC, and a combiner.
* The cell error determination circuit identifies amplitude and/or skew errors in each cell of the main DAC and generates error data.
* The correction DAC generates an error signal based on the error data.
* The combiner combines the error signal with the main DAC output to correct errors in the DAC.

==Key Features and Innovation==
* Correction of amplitude and/or skew errors in a DAC.
* Use of a correction DAC to adjust the output of the main DAC based on error data.
