Abstract
A logic circuit contains a first transistor with a logic signal supplied to the base and having its collector connected to an output node. A second transistor has a collector connected to the emitter of the first transistor and an emitter connected to a reference potential, in which the collector current supplied to the first transistor corresponds to the level of the control signal supplied to the base. A p-channel insulated gate field-effect transistor is connected between the power supply and the output node, and a first bias circuit supplies a bias voltage to the gate of the p-channel insulated gate field-effect transistor as the load. An n-channel insulated gate field-effect transistor is connected between the power supply and the output node and parallel to the p-channel insulated gate field-effect transistor as the load, and a second bias circuit supplies a bias voltage to the gate of the n-channel insulated gate field-effect transistor.
