Abstract
Presented is an integrated asymmetric resonant tunneling diode pair circuit exhibiting current-voltage characteristics providing multistable states which may be tailored for multistable solutions. Also presented are apparatus incorporating the invention therein, for which the invention provides a simple, integrated design that greatly reduces circuit complexity and size. The present invention is useful in all applications utilizing multiple peak characteristics of the current-voltage curve, such as multiple-valued logic analog-to-digital quantizers, frequency multiplication devices, waveform scrambling devices, memory operations, and parity-bit generation, among others.
