    摘要： A layered structure is divided into a plurality of regions. Transmission line equivalents (Green's functions) in the spectral domain are formed between all regions within the layered structure. The spectral domain Greens' function are converted to the spatial domain using a near field and a far field computed for those regions part of a component within the layered structure. The far field is extracted from a compressed database computed from the transmission line equivalents and descriptive of the layered structure. The near field is computed using a prioritization mechanism. Priority is assigned in accordance with the amplitude of a source and the length of the path between regions of interest.Once the physical characteristics of the layers used in the fabrication process of the IC are identified, the database used for computation of the far field is compiled and compressed, and remains unchanged for each new parameter extraction. Thus, compressed, layered Green's functions in the database decouple the computation of the far field from the layer structure and circuit geometry, minimizing computation time.

    摘要： An MCM including a resonator made using conventional MCM fabrication techniques. The MCM's resonator is constructed with overlapping first and second spiral-shaped regions of metallic material separated by a layer of dielectric material. A via disposed in the layer of dielectric material, couples the spiral-shaped regions of metallic material together, thereby utilizing self winding and internal capacitance to gain resonance at frequencies between 500 MHz to 3GHz. The internal capacitance is increased by controlling the overlap between the first and second spiral-shaped regions of metallic material. On a high-resistivity substrate, the monolithic resonator achieves a Q of at least 19 at approximately 900MHz and at least 24 at approximately 2GHz.

    摘要： A component design tool extracts a parameter associated with a component defined in a model of a physical system. The design tool discretizes the component and generates a matrix representative of a specified parameter. By subdividing the matrix into a hierarchy of submatrices and iteratively compressing and blending the submatrices, the design tool produces a compressed matrix. The compressed matrix is efficiently solved using iterative techniques. From the solution of the matrix, the design tool calculates the specified parameter.
