Latest Patents

One of his latest patents is titled "Providing secondary power pins in integrated circuit design." This invention involves an integrated circuit (IC) design that incorporates multiple metal layers containing cells that require a secondary power supply. The design strategically places cells and stripes of a primary power/ground grid in the metal layers, while specific cells are equipped with secondary power stripes in a first metal layer. These secondary power stripes are engineered to fully overlap with corresponding primary power/ground grid stripes in different metal layers. This innovative approach allows for efficient routing of signals and the generation of power vias between the primary and secondary power/ground stripes.

Another notable patent is "Creating integrated circuit capacitance from gate array structures." This patent discloses techniques for utilizing gate arrays to create capacitive structures within an integrated circuit. The embodiments involve placing a gate array of P-type field effect transistors (P-fets) and N-type field effect transistors (N-fets) in the IC design. The drains and sources of the P-fets are coupled to a power supply ground, while the gates of the P-fets and the drains and sources of the N-fets are connected to a positive voltage. This design minimizes source-to-drain leakage current for the capacitive apparatuses, enhancing the overall performance of the integrated circuit.
