Abstract: PURPOSE:To obtain a signal whose phase is not inverted by branching a part of an input signal current to a double balanced differential amplifier by a transistor (TR), applying control only to the remaining input current after the branching, synthesizing the control current and the branched current so as to form an output current. CONSTITUTION:A base of a TRQ7 is connected to an input signal source VS and a collector is connected respectively to an output terminal O1. On the other hand, the base of a TRQ8 is connected to a reference voltage source Vref. the collector is connected to an output terminal O2 and the emitter is connected to a current source IO respectively. Collector currents ic3, ic4 of TRs Q3, Q4 are obtained by dividing the collector current ic1 of the TRQ1 by a ratio decided by a control voltage Vc. The output current amplitude i1 always takes a negative value and an output current amplitude i2 always takes a positive value and no output phase inversion is caused. The output current i2 is amplified monotonously from the minimum amplitude zero to the maximum amplitude iOVs/4VT in response to the increase in the control voltage Vc without phase inversion.
