A method and apparatus for use in improving linearity sensitivity of MOSFET devices having an accumulated charge sink (ACS) are disclosed. The method and apparatus are adapted to address degradation in second- and third-order intermodulation harmonic distortion at a desired range of operating voltage in devices employing an accumulated charge sink.

Method and apparatus for use in improving linearity of MOSFETs using an accumulated charge sink-harmonic wrinkle reduction

A fast response time, self-activating, adjustable threshold limiter including a limiting element LE, a first coupling element CEelectrically connected from a signal node of LE to a control input of LE, and a second coupling element CEelectrically connected from the control input of LE to a nominal node of LE. An initial bias (control) voltage is also supplied to the control input of LE to dynamically control the limiting threshold for the limiter. Embodiments include usage of self-activating adjustable power limiters in combination with series switch components in a switch circuit in lieu of conventional shunt switches.
