  • Method to reduce power in active shield circuits that use complementary traces
    Patent number: 7622944
    Abstract: The present invention provides a method and apparatus for securing an integrated circuit. A pair of conductive security traces are arranged on an integrated circuit. Driver means provide complementary HIGH and LOW voltage levels to a respective first end of each of the conductive security traces. A first switch means temporarily interrupts the driver means and isolates the pair of conductive security traces. A second switch means temporarily connects the first ends of the isolated pair of conductive security traces to each other so that both conductive traces are at the same voltage. The voltage at the first end of one of the security traces at the LOW voltage is then boosted to one-half of the HIGH voltage level (VDD/2) by the HIGH (VDD) voltage level at the first end of the other security trace.
