Abstract
A semiconductor logical device provides one or a plurality of first field effect transistor(s) which perform a switching operation in accordance with an input signal input to a gate contact thereof, a first element which is constituted by a field effect transistor whose gate and source contacts are subjected to short-circuit, and which is connected as a load of the first field effect transistor, a second element which is constituted by a field effect transistor whose gate and source contacts are subjected to short-circuit and which is connected in series to the first element to act as a load of the first field effect transistor, a source follower circuit for power-amplifying a signal which is generated in the gate-source contact of the first element, and a second field effect transistor whose drain contact is connected to the gate-source contact of the second element, whose source contact is connected to an anode contact of a diode which generates a desired voltage, and to whose gate contact an output signal of the source follower circuit is applied.
