ABSTRACT:
In a differential amplifier with asymmetrical outputs, the gates of the two load transistors are at the same specified potential and the voltage at the connection node between the load transistor and the amplifier transistor of one arm is stabilized by means of a compensation structure. This amplifier works at low VCC (e.g., less than 2 volts) while at the same time having high gain.
