Reliable Oscillatory Neural Network Utilizing a Thermally Stable Single Transistor-based Oscillator

A reliable oscillatory neural network (ONN) is demonstrated using a thermally stable single transistor-based oscillator (1T-oscillator). Instead of relying on thermally sensitive impact ionization (I.I.), thermally insensitive band-to-band tunneling (BTBT) is utilized to trigger a single-transistor latch (STL), ensuring stable oscillation characteristics. The study investigates the properties of coupled oscillators, the fundamental elements of ONN, across different temperature settings to confirm thermal stability effects. Additionally, the reliability of ONN is verified through a vertex coloring task, a representative problem in nondeterministic polynomial time hard (NP-hard) combinatorial optimization.
