Abstract

PURPOSE: To perform a sure logical operation by setting the collector area according to the magnitude of the current supplied to the gate by using two logical gates.
CONSTITUTION: Two logical gates G21 and G22 are used; and the output of gate G21 is connected to the input of gate G22, and the output of gate G22 is connected to the input of gate G21. At the same time, the supply current dependent upon the injector of gate G22 is made smaller than that dependent upon the injector of gate G21, and further, the area of the collector which becomes the output of gate G22 connected to the input of gate G21 is made larger than that which becomes the output of gate G21 connected to the input of gate G22. As a result, when the collector area is set according to the supply current of the gate, a sure logical operation can be performed.
