Abstract

PURPOSE: To achieve power amplification with no distortion and high accuracy easily, by connecting a plurality of output current amplifiers parallelly between a voltage amplifier and a load amplifying non-distortion, performing negative feedback to a voltage amplifier from each output terminal and cancelling the distortion between the current amplifiers.
CONSTITUTION: Current amplifiers B0 and C1 are respectively provided between a voltage amplifier A with no distortion and loads Z1, Z2. Negative feedback is made from the output side of the current amplifiers B0 and C1 via resistors R2, R3 respectively. Thus, the distortion caused in the amplifiers B0, C1 can be cancelled. As a result, since no auxiliary output current amplifier without distortion can be required, the power amplificatin with high accuracy without distortion can be made.
