Abstract
In an embodiment a shunt driver circuit has a first and a second connection terminal (N, N) forming a two-wire interface (N, N), the first connection terminal (N) being prepared to receive a supply power and to provide an output signal (Sout), the second connection terminal (N) being connected to a reference potential terminal (), an Operational Transconductance Amplifier, OTA, () comprising a first input coupled to the first connection terminal (N), a second input for receiving a first reference signal (Sref) and an output () for providing a signal (S) depending on a difference between an input signal on the first input and the first reference signal (Sref), a capacitor (C) coupled between the output () and the first input of the OTA () via the second connection terminal (N) in a control loop, and a controlled current source () coupled between the output () of the OTA () and the second connection terminal (N). The controlled current source () is controlled to provide an additional current (Ifall) during a transient phase of the output signal (Sout).
