  • Programmable integrated circuit having metal plate capacitors that provide local switching energy
    Patent number: 6201411
    Abstract: Certain digital logic elements within the core of a field programmable integrated gate array (FPGA) require relatively large spikes of supply current when they switch. Local integrated metal plate bypass capacitors are provided in the core of the FPGA near the digital logic elements. The local integrated bypass capacitors provide the digital logic elements with a substantial portion of the required spikes of supply current. The magnitude of supply current spikes drawn over resistive and/or inductive power leads from the edges of the FPGA is therefore reduced and associated drops in supply voltage at the core are reduced.
    Type: Grant
