PURPOSE:To decrease the power consumption of the circuit and to speed up the operation of a logical circuit by constituting a complementary circuit with a composite transistor (TR) and also forming an output circuit as an emitter (source) follower circuit. CONSTITUTION:A logic circuit acting like an inverter is provided with a P-channel MIS TRQ3 of lateral structure and an n-channel MISTRQ4 of lateral structure. Further, npn TRQ5 and pnp TRQ6 of vertical structure are provided respectively, the gates of the TRQ3, Q4 are connected mutually and an input signal IN is inputted to the connecting point. Moreover, a base of the TRQ5, Q6 is connected respectively to a drain of the TRQ3, Q4, a V+ side of a power supply is connected to the source of the TRQ3 and a V- side of the power supply is connected to a source of the TRQ4. Then a collector of the TRQ5, Q6 is connected to the V+ and V- sides of the power supply and an output signal OUT is extracted from emitters in common connection. Then the power consumption of the circuit is reduced and also the effect of a load capacitance is eliminated thereby attaining high speed operation. |
