More Information
Summary:A correction system is configured to correct for duty cycle distortion and/or cross-point distortion in a pair of sample signals. A slope adjustment circuit is configured to generate a plurality of pairs of intermediate signals according to a plurality of drive strengths. A measurement circuit is configured to measure for duty cycle distortion and/or cross-point distortion, and the slope adjustment circuit is configured to set the plurality of drive strengths based on the measurement. The setting of the drive strengths may reduce certain rising and falling slopes of certain transitions of the plurality of intermediate signals, which in turn may reduce duty cycle distortion and/or cross-point distortion in the sample signals.
