Description: A Amplifier This is done by biasing the stage around the middle of its course between cut off and saturation points. More exactly the stage should be biased to dissipate the max power with no input signal, but sometime to centre the linearity of the transfer curve the bias point is shifted from the max dissipation point. The JFA has six single ended Jfet stages working in this way. The sixth stage has no gain; it simply acts as phase inverter of the signal already available at PIN 8.
