Analog-to-digital converter for quantizing two inputs and quantization method

The invention belongs to the technical field of data quantization processing in an integrated circuit. The invention discloses an analog-to-digital converter capable of quantizing two inputs simultaneously and a quantization method. The analog-to-digital converter is used for simultaneously quantizing two single-ended signals to be quantized, and comprises two digital-to-analog converters which are respectively connected to a positive input end and a negative input end of a comparator and used for sampling input signals or benchmark reference signals at the positive end and the negative end; acomparator which is used for receiving the input signals sampled by the two digital-to-analog converters and comparing and calculating a quantization difference value of the two input signals; a digital control circuit which is used for controlling the quantization state of the analog-to-digital converter. In conclusion, compared with a traditional analog-to-digital converter, the analog-to-digital converter has the adva
