Patent 9461037 was granted and assigned to PEREGRINE SEMICONDUCTOR CORP. on October, 2016 by the United States Patent and Trademark Office.
A structure and method for reducing second-order harmonic distortion in FET devices used in applications that are sensitive to such distortion, such as switching RF signals. The asymmetry of the drain-to-body capacitance Cdb and source-to-body capacitance Csb of a FET device are equalized by adding offsetting capacitance or a compensating voltage source.
