    Sammanfattning : Microelectronics is heading towards larger and larger systems implemented on a single chip. In wireless communication equipment, e.g., cellular phones, handheld computers etc. LÄS MER

  5. 4. Substrate Noise Coupling in Mixed-Signal Integrated Circuits: Compact Modeling and Grounding Strategies

    Författare :Simon Kristiansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active noise reduction; substrate noise coupling modeling; elliptic integrals.; grounding resistance; Mixed-signal integrated circuits; z-parameter; substrate resistance; surface potential;

    Sammanfattning : Integration of digital and analog circuits on the same chip is the result of the microelectronic industry's strive for low-cost, small, hand-held products. However, these mixed-signal circuits can experience interference problems; digital circuits inject noise into the substrate which is transmitted throughout the chip and received by sensitive analog circuits.
