More Information
Summary:An impedance matching circuit is provided. The impedance matching circuit includes a reference voltage generator configured to generate a reference voltage. A code generator is configured to generate a first calibration code by comparing the reference voltage with a first voltage associated with a first node and a second calibration code by comparing the reference voltage with a second voltage associated with a second node. A first resistance unit is configured to supply the first voltage to the first node in response to the first calibration code to calibrate its resistance to be equal to a reference resistance. A second resistance unit is configured to supply the second voltage to the second node in response to the second calibration code to thereby calibrate its resistance to the reference resistance.
