Abstract
A JFET switch select circuit including a first current mirror system including a first high current mirror circuit referenced to high rail voltage and a first low current mirror circuit referenced to a low rail voltage, a second current mirror system including a second high current mirror circuit referenced to the high rail voltage and a second low current mirror circuit referenced to the low rail voltage, and a comparator circuit responsive to an input voltage and a reference voltage for directing current from a current supply circuit to one of the first and second high current mirror circuits and one of the first and second low current mirror circuits for saturating a switching device of one of the first and second high current mirror circuits to set a first output voltage proximate to a high rail voltage and for saturating a switching device of one of the first and second low current mirror circuits to set a second output voltage proximate a low rail voltage.
