Abstract:
An amplifier stage comprising:a first source follower including a first transistor comprising a first source, a first gate and a first drain, said first drain coupled with a first current source and a first differential output, said first gate coupled with a first differential input, said first source coupled with a second current source; a second source follower including a second transistor comprising a second source, a second gate and a second drain, said second drain coupled with a third current source and a second differential output, said second gate coupled with a second differential input, said second source coupled with a fourth current source; a distortion compensator coupled between said first source follower and said second source follower, said distortion compensator comprising a differential load; and wherein said distortion compensator is operative to remove second order distortion from a differential analog signal input to said first and second differential inputs.
