Dac for offset compensation
WebOct 8, 2024 · For DC-offset minimization a hybrid method based on AC coupling with very low cut-off frequency and DAC-controlled hardware balancer of ADC inputs was developed. The level of the DC component in the output spectrum after calibration is close to -70 dBFS. ... It was also examined how the performance of compensation varies over time after ... WebAn offset compensation scheme using a digital-to-analog converter (DAC) is disclosed. In some embodiments, a DAC is coupled to a circuit having an undesired current or voltage offset and is configured to at least in part compensate for the undesired current or voltage offset. For example, in some embodiments, the DAC injects current or voltage into the …
