Abstract
According to one embodiment, a circuit for compensating fluctuation of a base current of a transistor is presented. The transistor has a base connected with an input terminal. The compensation circuit is provided with a first transistor, a current mirror circuit and a second transistor. The current mirror circuit mirrors a current which is supplied to a base of the first transistor. Further, the current mirror circuit supplies the obtained mirror current to the base of the transistor to be compensated. A base of the second transistor is connected with the input terminal electrically. The second transistor causes an early effect in the first transistor.
