GROUND-LOSS DETECTION CIRCUIT

摘要

A ground-loss detection circuit for an integrated circuit, (IC) device including a first dynamic threshold metal oxide semiconductor (DTMOS) device operably coupled between a first ground plane of the IC device and at least one further ground plane of the IC device, at least one of the first and at least one further ground planes comprising an external ground connection of the IC device, at least one further DTMOS device operably coupled between the first and at least one further ground planes of the IC device in an opposing manner to the first DTMOS device, and at least one ground-loss detection component operably coupled to at least one of the first and at least one further DTMOS devices and arranged to detect a ground-loss for at least one of the first and at least one further ground planes based at least partly on a drain current of the at least one of the first and at least one further DTMOS device(s).
