Abstract :
This barrier height reference circuit consists of a voltage loop containing a Schottky diode voltage, V/sub d/, and the difference in voltages of an even number of Schottky diodes, /spl Delta/V. The diode difference voltage is established by operating two groups of diodes at different current densities. This circuit is, in a sense, a bandgap reference and its operation is similar to that of a conventional bandgap reference. The circuit is implemented in a low-power, ion-implanted, GaAs MESFET manufacturing process.
