Device for regulating the common mode voltage at the output of a balanced amplifier |
摘要 |
A device for regulating the common mode output voltage of a balanced amplifier having two differential outputs, including a differential stage providing a correction signal of the common mode voltage corresponding to the difference between a reference voltage and the average differential output voltage of the amplifier, and further including a current generator that sets a polarization current of the differential stage, the current generator being controlled by the output current of the balanced amplifier.
