Abstract
An Analog to Digital Converter (ADC), an analog-to-digital conversion method, and an integrated circuit including the ADC. The ADC includes an input adjustment buffer stage, a sub-ADC, and a sample switch. The sample switch is coupled between the output node of the input adjustment buffer stage and the input node of the sub-ADC. When the sample switch is opened, the input adjustment buffer stage is configured to switch between a first work state and a second work state according to a predetermined rule, and to adjust an input voltage signal of the input adjustment buffer stage based on transitions between the first and second work states. When the sample switch is closed, the input adjustment buffer stage is configured to provide an adjusted voltage signal to the input node of the sub-ADC, and the sub-ADC is configured to perform an analog-to-digital conversion onto the adjusted voltage signal.
