Patent ID: 7907000

Claim:
A circuit arrangement comprising: a signal input configured to be supplied with a voltage signal; a first operational transconductance amplifier (OTA) having a voltage input that is couplable to the signal input; at least one second OTA having a voltage input that is couplable to the signal input; at least one output capacitor which is couplable to an output of the first OTA and to an output of the at least one second OTA, wherein the outputs of the first OTA and of the at least one second OTA have an identical potential; a first switching element having first and second connections, the first connection being coupled to the signal input and the second connection being coupled to the voltage input of the at least one second OTA; a second switching element having first and second connections, the first connection being coupled to the output of the first OTA and the second connection being coupled to the voltage input of the at least one second OTA; a third switching element having first and second connections, the first connection being coupled to the output of the first OTA and the second connection being coupled to the output of the at least one second OTA; and a control input configured to be supplied with a control signal, wherein the first, second and third switching elements are configurable to be switched from a first switching state to a second switching state based on the control signal, and the respective switching element connects the respective first connection and the respective second connection in an electrically conductive manner only in the first switching state.
