Background calibration of adc reference voltage errors due to input signal dependency |
摘要 |
Embodiments of the present invention may provide an analog-to-digital converter (ADC) system. The ADC system may include an analog circuit to receive an input signal and a reference voltage, and to convert the input signal into a raw digital output. The analog circuit may include at least one sampling element to sample the input signal during a sampling phase and reused to connect to the reference voltage during a conversion phase, and an ADC output to output the raw digital output. The ADC system may also include a digital processor to receive the raw digital output and for each clock cycle, to digitally correct reference voltage errors in the analog-to-digital conversion. |
