A field effect transistor having a doping concentration profile selected to linearize the relationship between the transconductance of the transistor and the level of a gate voltage fed to the gate electrode of such transistor over the operating range of such voltage. A first doping concentration profile is "spike-shaped" so that the bottom of the depletion zone and hence the transconductance is substantially invariant with gate voltage level. A second doping concentration profile, N(x), varies substantially as 1/x3 (where x is the depth from the surface of the transistor) over the operating range of the bottom of the depletion zone.
