Abstract :
In this paper we present a unity-gain follower amplifier based on a gated diode operated in breakdown regime in common cathode configuration. The amplifier has only one stage and it provides power amplification, high input impedance and a low output one. The maximum frequency that can be applied on the entrance of the amplifier so that the output remains undistorted is dependent on the bias current therefore it can be used also as a programmable low pass filter. The diode is fully characterized in order to set the bias in the linear region where the amplification is very close to one.
