Abstract
The performance of JFET as a switch in the feedback loop of a multigai n ranging current electrometer is described, The study indicates that the electrometer starts departing from linear behavior as the input cu rrent becomes comparable to the drain saturation current of the JFET. It is shown that the nonlinearity in the electrometer behavior is attr ibutable to the variations occurring in the ON resistance and gate cur rent of the JFET.
