Abstract
Signals applied to the gate of an enhancement-mode field effect transistor by resistive coupling, via a dc-blocking capacitor, are self-biased. The self biasing is carried out by detecting the signal amplitude and applying a portion of the direct voltage from this detection to the gate of the field effect transistor through the coupling resistor.
