  • Clamp networks to insure operation of integrated circuit chips
    Patent number: 7760004
    Abstract: Clamp networks are provided to insure successful operation of a variety of electronic circuits that are realized in the form of integrated circuit chips. These networks are especially suited for use in chips in which on-chip circuits generate a voltage to bias the chip substrate relative to the chip ground. The clamp networks are configured to drive a current between the chip ground and the chip substrate whenever the chip substrate begins to rise above the chip ground during turn on of the chip input voltage. The clamp networks thus insure that the chip substrate is properly biased when the input voltage has been established and that the chip, therefore, functions as intended.
    Type: Grant
