    摘要: An on-chip capacitive device comprises a semiconductor substrate, a MOS capacitor formed on the semiconductor substrate, and a metal interconnect capacitor formed at least in part in a region above the MOS capacitor. The MOS capacitor and the metal interconnect capacitor are connected in parallel to form a single capacitive device. The capacitance densities of the MOS capacitor and the metal interconnect capacitor are, thereby, combined. Advantageously, significant capacitance density gains can be achieved without additional processing steps.

    摘要: A parameterizable design system is for use with semiconductor analog circuits and includes an interface unit connected to provide access to the system, a database unit connected to supply a library of parameterizable analog building blocks for a design entity, and a parameterization unit connected to select a parameter for one of the library of parameterizable analog building blocks to meet a design specification of the design entity. Additionally, the parameterizable design system may also include a simulation unit connected to simulate an operation of the design entity employing the parameter, and an analyzer unit connected to analyze a sensitivity of the parameter for the design entity based on the design specification. A method of designing a semiconductor analog circuit is also included.
