Patent attributes
Described are embodiments of stacked field effect transistor (FET) switch having a plurality of FET devices coupled in series to form an FET device stack. A control circuit provides biasing voltages to the gate, source, and drain contacts of each of the plurality of FET devices to switch the FET device stack to and from a closed state and an open state. In the open state, the gate contacts of each of the plurality of FET devices are biased by the control circuit at the second voltage. To prevent activation in the open state, the control circuit biases the drain contacts and source contacts of each of the plurality of FET devices at the first voltage. The first voltage is positive relative to a reference voltage, such as ground, while the second voltage is non-negative relative to the reference voltage but less than the first voltage.
