ABSTRACT:
A method for cascading a first amplifier stage and a second amplifier stage includes coupling the output terminal of the first amplifier stage to the power supply reference point of the second amplifier stage, modulating the power supply reference point of the second amplifier stage using the output current of the first amplifier stage, and generating a final output voltage at the output terminal of the second amplifier stage having a first voltage value relative to the power supply reference point of the first amplifier stage. The first voltage value is the sum of the output voltage of the first amplifier stage relative to its own power supply reference point and the output voltage of the second amplifier stage relative to its own power supply reference point. In one embodiment, the power supply reference point is the ground reference of the power source in the amplifier stage.
