Abstract

The present disclosure relates to an apparatus including level shifter circuitry configured to convert a voltage between one or more multi-voltage domains. The apparatus may include an integrated circuit having a cross-coupled latch including a first weak transistor cross-coupled with a second weak transistor. The integrated circuit may further include a first strong transistor in parallel with the first weak transistor and a second strong transistor in parallel with the second weak transistor. The integrated circuit may further include an inverter configured to toggle at least one of the first weak transistor and the second weak transistor.
