  • Method and apparatus for error current compensation
    Patent number: 6160390
    Abstract: A method and circuit for error current compensation is presented. The method includes the steps of generating a first current and an associated error current, generating a second current and an associated error current substantially equal to the first current and the first error current, respectively, and generating a third current substantially equal to the first current. The method includes the additional steps of extracting the second error current from the second current, generating a multiplied current equal to the scaled error current plus a multiplier error current, and combining the multiplied current with the first current and first error current.The circuit for error current compensation includes a first, second and third current source, a multiplier, and a first and second subtractor.
