LinkedinThe "musician preferred" instruments of yesteryear all used FET amplifiers. Simply because their acoustics sounded better than Biplolar linear transistor amplification. FET amplifiers are not linear, nor do they need coupling capacitors on their gate leads. Although "near-linearity", would reduce harmonic distortion in an all FET amplifier that seeks to restore the "musician's endorsement.
Because of that issue and my personal lack of resistance to curiosity, I would like to propose a two or more stage FET amplifier with a more flattened Transconduction Curve, to serve as an amplifier for acoustics reproduction.
In theory, the Drain current of one FET can be direct coupled to the gate of another FET, or several FET' s in a multi-stage amplifier. And since the gate of an FET is mostly voltage driven, subsequent FET's would be driven by the voltage across the preceding FET's Drain resistor. And my intent is to compensate for the non-linearity of the first FET with the non-linearity of the subsequent FET(s). The effect should be a flattening of the Transconduction Curve at each stage of amplification. Which is my proposed more-linear FET amplifier for acoustics reproduction.
