Abstract: RF switching circuitry includes an RF switch coupled between an input node and an output node. Distortion compensation circuitry is coupled in parallel with the RF switch between the input node and the output node. The RF switch is configured to selectively pass an RF signal from the input node to the output node based on a first switching control signal. The distortion compensation circuitry is configured to boost a portion of the RF signal that is being compressed by the RF switch when the amplitude of the RF signal is above a predetermined threshold by selectively injecting current into one of the input node or the output node. Boosting a portion of the RF signal that is being compressed by the RF switch allows a signal passing through the RF switch to remain substantially linear, thereby improving the performance of the RF switching circuitry.

Abstract: Switchable capacitive elements are disclosed, along with programmable capacitor arrays (PCAs). One embodiment of the switchable capacitive element includes a field effect transistor (FET) device stack, a first capacitor, and a second capacitor. The FET device stack is operable in an open state and in a closed state and has a plurality of FET devices coupled in series to form the FET device stack. The first capacitor and the second capacitor are both coupled in series with the FET device stack. However, the first capacitor is coupled to a first end of the FET device stack while the second capacitor is coupled to a second end opposite the first end of the FET device stack. In this manner, the switchable capacitive element can be operated without a negative charge pump, with decreased bias swings, and with a better power performance.
