A precision voltage level shift circuit includes an emitter follower input circuit including a lateral PNP transistor having a base receiving an input voltage, and an emitter coupled to both an output terminal and a first current source. JFET is coupled between a collector of the input transistor and a first supply voltage conductor. A second PNP transistor has a base coupled to the collector of the first transistor and an emitter coupled to a second current source. A differential amplifier has a first input coupled to the output terminal, a second input coupled to the emitter of the second transistor, and an output coupled to the load element. The differential amplifier operates to maintain the voltage drop across the JFET at a level such that the emitter of the second PNP transistor is equal to the voltage of the emitter of the lateral PNP transistor to thereby maintain the collector-emitter voltage thereof at a constant value. Two of the voltage level shift circuits are used as input stages for an instrumentation amplifier.
