Abstract

An integrated circuit (IC) includes a set of metastability-hardened storage circuits. Each metastability-hardened storage circuit may include: (a) a pulse width distortion circuit; (b) a first circuit powered by a nominal power supply voltage, and a second circuit powered by a higher-than-nominal supply voltage; (c) an inverter and a bias circuit, where the bias circuit provides a bias current based on an intermediate state of the inverter to resolve a metastable state of the inverter; or (d) a latch, and a dynamic bias circuit that causes current to be injected into the latch to resolve a metastable state of the latch.
