Abstract
Systems and techniques for Digital-to-Analog Converter (DAC) gain correction are described herein. A digital-to-analog converter (DAC) circuit can include a switch bridge circuit having a first leg and a second leg that define respective mutually exclusive first and second DAC signal paths. The DAC circuit can further include a first compensation circuit configured to provide a first compensation current to the first leg of the switch bridge to compensate for a current defect caused by a voltage drop across a portion of the first DAC signal path. The DAC circuit can also include a second compensation circuit configured to provide a second compensation current to a second leg of the switch bridge to compensate for a voltage drop across a portion of the second DAC signal path. The DAC circuit can be included in a larger circuit such as a continuous time sigma delta (CTSD) analog-to-digital converter (ADC).
