Abstract
A circuit arrangement () for driving an electrical load () comprises an input () for feeding a power-supply voltage (Vs) with an AC component and an output () for providing an output signal (Sout) for driving a connectable electrical load (). The circuit arrangement () further comprises a frequency processing circuit () for proving a reference frequency (f) as a function of the AC component, and a demodulator () with a first input () for feeding the reference frequency (f), with a second input () that is coupled to the input () of the circuit arrangement (), and with an output () that is coupled to the output () of the circuit arrangement ().
