Abstract
The disclosure relates to a circuit for compensation for ground glitches in an integrated circuit wherein there is provided a glitch fix circuit wherein a node is responsive to a negative shift in the level of ground relative to Vcc to turn on a transistor and drain current to ground from the input circuits to transistors in the circuit under control. A feedback circuit is provided which is out of phase with the circuit input of the circuit being controlled and which is one Von above ground. This feedback circuit inhibits the glitch fix circuit in the event that the increase in voltage difference between the input to the circuit being protected and ground is a result of a high input signal rather than noise which lowers the ground level.
