In such a case, a current ID flows through both the TRs Mp1 and Mn2 and a voltage V1 is produced across a resistor R5. The voltage V1 is set to be larger than the sum of the base-emitter voltage VBE4 of a TR Q4 and the base-emitter voltage VBE3 of a TR Q3. Thus, the TR Q4 is turned on and an emitter current IB' is added to the base current IB of the TR Q3. That is, the total current of the current IB'' supplied via the 1st TR Mn1 and the current IB' supplied via the Q4 is used as the base current of the TR Q3 and its turn-on is quickened.
