Abstract
The present document relates to differential amplifiers. A differential amplifier may comprise a current source, a first transistor, a second transistor, and a compensation circuit. A reference voltage may be applied to a first terminal of the first transistor, and a second terminal of the first transistor may be coupled to an output of the current source. A feedback voltage may be applied to a first terminal of the second transistor, and a second terminal of the second transistor may be coupled to the output of the current source. The compensation circuit may comprise a capacitive element coupled to the first terminal of the first transistor, and the compensation circuit may be configured to reduce a change of the reference voltage at the first terminal of the first transistor.
