A dual-sided MOS IC includes an isolation layer and a MOS transistor. The isolation layer separates the MOS IC into a MOS IC frontside and a MOS IC backside. The MOS transistor is on both the MOS IC frontside and the MOS IC backside. The MOS transistor includes MOS gates, a first source connection in a first subsection of the MOS IC frontside, and a second source connection in a second subsection of the MOS IC backside. The first and second source connections are electrically coupled together through a first front-to-backside connection extending through the isolation layer. The MOS transistor further includes a first drain connection in the first subsection of the MOS IC backside, and a second drain connection in the second subsection of the MOS IC frontside. The first and second drain connections are electrically coupled together through a second front-to-backside connection extending through the isolation layer.

Symmetric dual-sided MOS IC

An RF switching device having distributed shunt switches distributed along transmission lines to improve RF bandwidth as well as the signal isolation of the device. The shunt switches may be physically positioned on both sides of the transmission lines to keep an integrated circuit (IC) design essentially symmetrical so as to provide predictable and reliable operational characteristics. Some embodiments include stacked FET shunt switches and series switches to tolerate high voltages. In some embodiments, the gate resistor for each FET shunt switch is divided into two or more portions.

Radio frequency switching circuit and distributed switches

A high performance integrated tunable impedance matching network with coupled merged inductors. Embodiments include a combination of merged multiport constructively coupled spiral inductors and tunable capacitors configured to reduce insertion losses, circuit size, and optimization time while maintaining a high Q factor for the coupled spiral inductors. Some embodiments integrate one or more filter circuits with a tunable impedance matching network, useful in conjunction with such applications as radio frequency power amplifiers.
