Abstract

PURPOSE: To reduce area of a chip by making up monitor elements of the same kind as constituent elements of an integrated circuit in a semiconductor chip constituting an integrated circuit and using one of electrodes for the monitor element and one of electrodes for the integrated circuit in common.
CONSTITUTION: Differential amplitude circuits, for instance, which is composed of seven NPN transistors 1W7 are integrated and formed in a semiconductor chip. In this chip is mounted an independent monitor transistor 8 and by measuring the characteristics, VCEO, ICEO of this monitor transistor 8 are controlled characteristics of the amplitude circuit transistor. If one of electrodes of the monitor transistor 8, for example, an emitter electrode is used in common with an electrode of the amplitude circuit, for example, a ground electode 11, the area of electrodes is reduced and the chip size can be lessened. This method is used independently of circuit structure of integrated circuits, of active or passive kinds of monitor elements, of kinds of common electrodes for the ground or not.
