An amplifier having at least a drive stage and an output stage, the output stage comprised of an FET for applying an amplified signal to a load. The drive stage includes a transistor device whose output is direct coupled to the gate electrode of the FET, the transistor device being supplied with an input signal to be amplified. A constant current source is coupled to the output of the transistor device, and thus to the gate electrode of the FET, and provides a current of predetermined magnitude to thus limit the gate leakage current during periods that the FET is cut off. |
