Abstract
Electronic switch () with two switching states (ON, OFF) possesses at least one field effect switching transistor (Q), input port (In) connected with source terminal (S), on which input signal (Vin) is present, output port (Out) connected with drain terminal, on which switched signal (Vout) is present, control port (Con) connected to gate terminal (G), on which is present signal (Vc) for controlling electronic switch () and switch apparatus (Sw), which creates the two switching states (ON, OFF) by means of a changing of control signal (Vc). Controlling signal (Vc), during at least one of the two switching states (ON, OFF) is, at least partially, formed by correction signal (Sc), which in turn is produced from input signal (Vin), so that the frequency dependent drop in voltage between the drain-source channel and the gate electrode of the field effect switching transistor (Q) is at least partially compensated.
