PURPOSE:To facilitate the offset adjustment by connecting a current Miller connected transistor couple having a controlling resistance in one emitter electric circuit and a current Miller connected transistor couple connected thereto as active load to a power source driving transistors. CONSTITUTION:A current source connection unit having transistors Q1 and Q2 and first and second current Miller connected transistor blocks respectively comprising transistors Q3-Q7 and Q8-Q10 are arranged and the first resistance R1 and the second resistance R2 and a load resistance R3 are connected thereto. Then, a current source made up of a Wiedemann type current Miller circuit comprising transistors Q11-Q14 and a resistance R4 and transistors Q15-Q16. Thus, the temperature offset level can be adjusted as desired by varying the resistance R4. |
