ABSTRACT:
Signal distortions are avoided without the assistance of external component parts in an integrated circuit arrangement for voltage control of the gain of a field effect transistor having at least first and second gate electrodes. The first gate electrode forms the signal input and the second gate electrode forms the DC voltage control input. An integrated control circuit arrangement is provided which sets the voltage at the first gate electrode of the field effect transistor dependent on a variable voltage at the second gate electrode thereof, whereby the source potential remains unaltered.
