Abstract
A switch device for switching an analog electrical input signal includes: a switching transistor being a flipped-well-silicon-on-insulator-NMOS transistor; and a bootstrapping arrangement including a voltage providing arrangement for providing a floating voltage during the on-state, wherein the floating voltage is provided at a positive terminal and at a negative terminal of the voltage providing arrangement; wherein the bootstrapping arrangement is configured in such way that during the on-state the positive terminal is electrically connected to the front gate contact of the switching transistor and to the back gate contact of the switching transistor, and the negative terminal is electrically connected to the source contact of the switching transistor; wherein the bootstrapping arrangement is configured in such way that during the off-state the positive terminal and the negative terminal are not electrically connected to the switching transistor.
