Abstract
An successive approximation register analog-to-digital converter is provided. The successive approximation register analog-to-digital converter includes a digital-to-analog converter, a successive approximation register, a comparator, and a threshold voltage determining unit. In this context, the threshold voltage determining unit is configured to dynamically determine the threshold voltage of the comparator on the basis of the input signal of the digital-to-analog converter or the output signal of the comparator.
Claims15
A successive approximation register analog-to-digital converter (SAR-ADC) comprising:
- a digital-to-analog converter (DAC);
- a successive approximation register (SAR);
- a comparator;
- and
- a threshold voltage determining unit (TVDU),
- wherein the TVDU is configured to set a threshold voltage of the comparator based on an input signal of the DAC or an output signal of the comparator.
A method comprising setting a threshold voltage of a comparator of a successive approximation register analog-to-digital converter (SAR-ADC) based on an input signal of a digital-to-analog converter (DAC) of the SAR-ADC or an output signal of the comparator.
