A circuit arrangement for transferring a signal from a first A.C. circuit point to a second A.C. circuit point includes a resonant circuit and a current mirror. The input of the current mirror is connected to the resonant circuit, while its common emitter terminal is connected to the first A.C. circuit point and its output is connected to the second A.C. circuit point. In this manner one side of the resonant circuit may be grounded, even though the resonant circuit is effectively inserted between the two A.C. circuit points which are isolated from ground.
