Abstract

Using a new circuit design and double-stacked junction technology we have demonstrated fully functional high-resolution programmable voltage standard chips with 67 410 junctions that operate up to 2.6 V maximum output voltage. The circuit uses double-stacked junctions, where two junctions are fabricated in each stack, in order to increase the output voltage. We have also improved the voltage resolution by designing a trinary-logic circuit instead of the typical binary-logic circuit. We find that these circuits operate over a frequency range from 14 GHz to 19 GHz with a 2 mA maximum operating current range.
