Abstract
A driver circuit is disclosed. In an embodiment a drive circuit includes a signal port with a first terminal and a second terminal, a first node and a second node, a comparator with an inverting input, a non-inverting input and an output and an operational amplifier with an inverting input, a non-inverting input and an output, wherein the first terminal is electrically conductively connected with the inverting input of the operational amplifier, wherein the second terminal is electrically conductively connected with the non-inverting input of the comparator, wherein the inverting input of the comparator is electrically conductively connected with the output of the operational amplifier, wherein the first node is electrically conductively connected with the output of the operational amplifier, wherein the inverting input of the comparator is electrically conductively connected with the inverting input of the operational amplifier, and wherein the second node is electrically conductively connected with the non-inverting input of the operational amplifier.
