ABSTRACT:
An inverter circuit according to this invention includes n- and p-type field effect transistors having predetermined wiring resistances and gates and drains connected with each other, a first power source connected to the source of the n-type field effect transistor, a power source connected to the source of the p-type field effect transistor, and first and second negative feedback switching transistors connected in parallel between the gates and the drains of the n- and p-type field effect transistors. Assuming that the channel length and width of the first insulating gate field effect transistor are L.sub.N and W.sub.N, respectively, and the wiring resistance thereof is R.sub.S, that the channel length and width of the second insulating gate field effect transistor are L.sub.P and W.sub.P, respectively, and the wiring resistance thereof is R.sub.D, and that carrier mobilities of the first and second insulating gate field effect transistors are .mu..sub.N and .mu..sub.P, respectively, a relation represented by: ##EQU1## is approximately satisfied. A voltage corresponding to a difference between a reference voltage and a comparison input is input from the connected gates, and data is output from the connected drains.
