ABSTRACT:
A level shifting circuit can include a first input junction field effect transistor (JFET) having a gate coupled to receive an input signal having a first voltage swing that provides a controllable impedance path between a first supply node and a first terminal of a first bias stack including at least one JFET. A driver circuit can be coupled to receive an output from the first bias stack that provides a level shifted output having a second voltage swing that is less than the first voltage swing.
