Abstract
Circuitry includes a floating-body main field-effect transistor (FET) device, a body-contacted cascode FET device, and biasing circuitry coupled to the floating-body main FET device and the body-contacted cascode FET device. The floating-body main FET device includes a gate contact, a drain contact, and a source contact. The body-contacted cascode FET device includes a gate contact, a drain contact coupled to a supply voltage, and a source contact coupled to the drain contact of the floating-body main FET device and to a body region of the body-contacted cascode FET device. The biasing circuitry is coupled to the gate contact of the floating-body main FET device and the gate contact of the body-contacted cascode FET device and configured to provide biasing signals to the floating-body main FET device and the body-contacted cascode FET device such that a majority of the supply voltage is provided across the body-contacted cascode FET device.
