Abstract
A circuit (12) for reducing positive ground bounce effects on an integrated circuit (10) of the type having an integrated circuit transistor (40) that has reduced conduction when exposed to a positive ground bounce potential includes circuitry responsive to an increase in ground potential to produce a drive current and circuitry for applying the drive current to the integrated circuit transistor (40) to oppose the reduced conduction. The positive ground bounce circuit (12) has a ground bounce sense transistor (56) of same conductivity type as the integrated circuit transistor (40), and a circuit (69) to bias the ground bounce sense transistor (56) normally into conduction to pass a control current. Since ground bounce sense transistor (56) also has reduced conduction when exposed to a positive ground bounce potential, a diode (72) is provided to redirect the control current to the integrated circuit transistor (40), thereby reducing the effects of a positive ground bounce condition.
