Abstract

PURPOSE: To obtain an output that is amplified having a phase opposite to the input without any negative feedback, by adding a current Miller circuit to an inverse-type amplifier.
CONSTITUTION: The current Miller circuit 21 is connected to the collector of the input transistor TRQ5 having an emitter-follower constitution to obtain the current I2 having a relation of a certain ratio with the current I1. The current I2 is supplied to the next current Miller circuit 22 to obtain the current I3 having a certain relation with the current I2. The current I3 is connected to the load resistance RL and compensating circuit 23 to extract an output out of an end of RL. The circuit 23 compensates the distortion caused by the base-emitter voltage VBE5 of the TRQ5. The output of the circuit 23 has a gain of N=RL/RE to have the output VOUT=VCC- NVIN+N(VBE5-VBE10). Then a control is given to both VBE5 and VBE10 to reduce the effect of VBE5.
