ABSTRACT:
A tunnel diode voltage reference circuit includes a tunnel diode; bias voltage circuit for biasing the tunnel diode to operate in the region of the peak current where the tunnel diode output current variation is a fraction of the bias voltage variation; and circuits responsive to the tunnel diode output current, for isolating the tunnel diode output from load variations and converting the tunnel diode output to a reference voltage. A resistance may be placed in parallel with the tunnel diode for raising the negative resistance region to the levels of the peak region to flatten the slope of the negative resistance region between the peak and the valley regions, reducing the reference voltage variation at bias points greater than the peak voltage of the tunnel diode characteristic.
