Differential amplifier

A differential amplifier comprising:

• an inverting input terminal;
• a non-inverting input terminal;
• an inverting output terminal;
• a non-inverting output terminal;
• an input differential pair that determines operating points of the inverting output terminal and the non-inverting output terminal;
• a common mode detection circuit, to which a reference signal is received, which generates a signal based on a differential between the reference voltage and an intermediate voltage of a voltage provided to the inverting input terminal and a voltage provided to the non-inverting input terminal;
• a first current generation circuit and a second current generation circuit, to which an output signal of the common mode detection circuit is provided, which generate currents in accordance with the output signal;
• a first transistor having a control terminal coupled to an output terminal of the first current generation circuit;
• a second transistor having a control terminal coupled to an output terminal of the second current generation circuit;
• a third current source having one end coupled to a node between one end of the first transistor and the non-inverting output terminal;
• a fourth current source having one end coupled to a node between one end of the second transistor and the inverting output terminal;
• a first circuit coupled between the inverting input terminal and the non-inverting output terminal;
• and
• a second circuit coupled between the non-inverting input terminal and the inverting output terminal.
