ABSTRACT:
A circuit and an adjusting method with a differential amplifier and with a control circuit, wherein the differential amplifier has a first amplifier transistor which for amplifying an input signal of the differential amplifier is connected in a first branch of the differential amplifier, wherein the differential amplifier has a second amplifier transistor which for amplifying the input signal of the differential amplifier is connected in a second branch of the differential amplifier, wherein the differential amplifier has at least one first series connection with a first transistor and a first semiconductor switch, the amplifier being connected parallel to the first amplifier transistor, wherein the differential amplifier has at least one second series connection with a second transistor and a second semiconductor switch, the amplifier being connected in parallel to the second amplifier transistor, and wherein the control circuit is connected to the switch inputs of the semiconductor switches to control the switching states of the semiconductor switches.
