Abstract
An output of a first amplifier is coupled to the input of a second amplifier by a coupling capacitor. A resistor connects one plate of the coupling capacitor to a reference voltage supplied by a potential divider. A field effect transistor is connected across the resistor with its gate connected to the connection between a further resistor and a further capacitor which are connected in series between power supply lines so that the coupling capacitor is rapidly charged when power is applied.
