Abstract
An amplifier circuit includes a first series circuit connected between a supply voltage and a reference potential. The first series circuit includes a current source, a first tap and a first component configured as a diode. The amplifier circuit also includes a second series circuit connected between the supply voltage and the reference potential, and includes a controlled path between a first connection and a second connection of a first transistor and a second tap. The control connection of the first transistor is coupled to the first tap. The second tap is used to output a bias voltage. The amplifier circuit includes an amplifier stage coupled to the second tap for setting an operating point of the amplifier stage.
