Abstract
Disclosed is a switching circuit which has: at least one unit circuit connected in series, the unit circuit being composed of two field-effect transistors connected in series and an inductor that has one end connected to a connection point between the two field-effect transistors and another end grounded; wherein the gates of the two field-effect transistors are commonly connected and a bias voltage to control the turning on/off of the two field-effect transistors is equally applied through a resistance to the respective gates. Also disclosed is a semiconductor device which has: at least one unit element connected in series, the unit element being composed of two field-effect transistors connected in series each of which has a source electrode and a drain electrode disposed sandwiching a gate electrode, one of the source electrode and the drain electrode being used as a common electrode, and a via hole disposed on a semiconductor substrate to connect the common electrode with a ground potential, the via hole operating as an inductor: and a resistance disposed on a gate bias line to apply a bias voltage to control the turning on/off of the two field-effect transistors equally to a plurality of the gate electrodes; wherein the plurality of the gate electrodes are commonly connected.
