Abstract
An analog-to-digital converting circuit includes a reference circuit and an analog-to-digital converter (ADC). The reference circuit provides a base voltage, which has one end grounded. The ADC receives an analog input signal and a base voltage signal. The ADC includes a first DC buffer and an ADC core unit. The first DC buffer internally receives an offset voltage signal and a data voltage signal to be digitized, and outputs two converting control signals. The ADC core unit receives the two converting control signals from the first DC buffer and an ADC input range voltage signal, and outputs a digital code. All of the offset voltage signal and the data voltage signal and the ADC input range voltage signal have been added with the base voltage signal.
