Amplifier having a symmetrical output characteristic |
摘要 |
A symmetrical amplifier includes a current mirror circuit and a current splitting circuit. The current splitting circuit splits up an input signal applied to the amplifier as a function of the signal polarity. Negative input currents are applied to the current mirror circuit whose controlled output current is applied to a control input of a first current amplifier circuit arranged in the amplifier. In order to insure symmetrical operation of the amplifier, positive input currents flowing into the amplifier are applied to a control input of a second current amplifier circuit arranged in the amplifier. The second current amplifier circuit is the same as the first current amplifier circuit. The first current amplifier circuit is connected to a positive supply voltage and the second current amplifier circuit is connected to a negative power supply voltage, and the two current amplifier circuits operate into a common load at their output ends.
