Abstract
A calculation code generation circuit performs calibration using a counter, and a digital correction circuit including the same. The calculation code generation circuit performs a calculation process according to first and second modes, the calculation process including generating a first code by sampling a first value of the count code, generating a second code by sampling a second value of the count code, generating first and second calculation codes using the first and second codes in the first and second modes, respectively, and generating, in a calibration disable state, a third calculation code using the first and second calculation codes generated in the first and second modes, respectively, to remove the influence of the comparison offset or comparison performance of a comparator, thereby removing a calibration error.
