Abstract
The circuits and methods of the present invention provide sample and hold circuits that incorporate an auxiliary sampling leg that cancels distortion produced in a main sampling leg of the sample and hold circuit. The auxiliary sampling leg of the circuit produces canceling distortion that is proportionally larger than the distortion produced in the main sampling leg. The distortion in the auxiliary sampling leg is then reduced in size so that the canceling distortion becomes proportionally equal to the distortion in the main sampling leg. Finally, the proportionally equal canceling distortion of the auxiliary sampling leg is subtracted from the distortion of the main sampling leg so that substantially all of the distortion is canceled out while retaining a substantial portion of the input signal.
