Abstract:
An Integrated Circuit (IC) as described herein may include a first logic circuit, a second logic circuit coupled to the first logic circuit via a level shifter, and a safe state circuit coupled to the first logic circuit and to a first input of a logic gate. For example, a second input of the logic gate may be coupled to an output of the level shifter, and an output of the logic gate may be coupled to the second logic circuit. The safe state circuit may further include a front-end portion; a reversible current mirror portion coupled to the front-end portion; and a voltage-level translation portion coupled to the reversible current mirror portion.
