ABSTRACT:
A JFET pair having unequal pinchoff voltages is operated in saturation with equal source-drain current to channel width-to-length ratios to provide a reference voltage output. Positive or negative voltage references can be implemented using either n-channel or p-channel JFETs. The pinchoff voltage difference results from the channel for one JFET having a heavier doping level than that of the other JFET.
