Patent ID: 6903426

Claim:
A semiconductor switching device comprising: a first field effect transistor and a second field effect transistor each comprising a source electrode, a gate electrode and a drain electrode which are formed on a channel layer of the respective transistor; a common input terminal connected to the source electrode or the drain electrode of the first transistor and connected to the source electrode or the drain electrode of the second transistor; a first output terminal connected to the source electrode or the drain electrode of the first transistor which is not connected to the common input terminal; a second output terminal connected to the source electrode or the drain electrode of the second transistor which is not connected to the common input terminal; a first control terminal and a second control terminal; a first resistor connecting the first control terminal and the gate electrode of the first transistor; and a second resistor connecting the second control terminal and the gate electrode of the second transistor, wherein the gate electrodes of the first transistor and the second transistor receive control signals so that one of the transistors opens as a switching element and the other of the transistors closes as another switching element, and the first resistor is more tightly configured than the second resistor so that the first transistor occupies a larger surface area than the second transistor.
