Beschreibung
Zusammenfassung:	An amplifier includes an input circuit that amplifies a difference between a first input voltage and a second input voltage to generate a first current and a second current. A positive feedback circuit amplifies a difference between the first current and the second current to generate a third current and a fourth current and outputs a difference between the third current and the fourth current through an output node. A temperature compensation circuit adjusts an amplification factor of the positive feedback circuit in response to a change of temperature.
