Abstract
A pair of n-peaked resonant tunneling diodes with series resistance are connected in series across a supply voltage to form a digitizer, which has 2n+1 stable operating points. There are n high current operating points and n+1 low current operating points, corresponding to "1" and "0" logic levels. For an n-bit analog-to-digital converter, the analog input voltage is divided into n binary-weighted fractions and applied to n digitizers, which latch the divided voltages into binary currents serving as digital output.
