Abstract
A source follower circuit using at least one FET in which an end of a resistor element is connected to the gate terminal of the FET and the other end of the resistor element is connected to a signal source which generates a comparatively large AC input signal. The resistance of the resistor element is determined to be at such a value as to prevent oscillation of the FET which is likely to occur depending on the length of the wiring between the signal source and gate terminal and the length of wiring between the source terminal and a load.
