A matching circuit for two-channel Analog to Digital Converters (ADCs) is disclosed in which two ADCs convert analog signals of two channels to digital signals with the same operational characteristics. A bias voltage supplier operates in such a way that analog signals of first and second channels are each converted to digital signals by first and second ADCs, a bias voltage supplier generates a DC bias voltage to set up DC levels of the analog signals of the first and second channels, and a reference voltage supplier generates a reference voltage and supplies it to the first and second ADCs. Therefore, the first and second ADCs convert the analog signals to digital signals with the same operational characteristics.
