Abstract
A method and apparatus for removing second order distortion is disclosed. The method couples a differential load between two source followers of a gain stage. The apparatus includes a differential load having two MOS transistors of unequal channel width/length ratios. The differential load implements a square and summing function in a single circuit eliminating the need to split the signal path.
