ABSTRACT:
An inverter circuit comprises a bipolar transistor having a collector and an emitter of a first conductivity type, and at least three field effect transistors of which the first one includes a channel of a second conductivity type, the second one includes a channel of the first conductivity type, and the third one includes a channel of the first conductivity type. The first field effect transistor with the channel of the second conductivity type is connected at the gate thereof to ground to be permanently turned on. As a result, the first field effect transistor is used as a load. The inverter circuit provides the reduction in the number of transistors typically used therein and decrease in an input capacitance, even if a multi-gate input structure is adopted.
