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

    Author : Simon Kristiansson; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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.

  4. 2. Life strategies for substrate assimilation by freshwater bacterioplankton

    Author : Monica Ricão Canelhas; Stefan Bertilsson; Jay T. Lennon; Uppsala universitet; []
    Keywords : lake; methane; bacteria; substrate; methanotrophs; pulse; chemostat;

    Abstract : The availability of substrates is one of the most important environmental constraints on the diversity and functioning of microorganisms. Substrate quantity and quality as well as the metabolic features of heterotrophic microorganisms determine the efficiency, speed and type of transformation that can occur in nature. READ MORE

  5. 3. Reduction of Substrate Noise in Mixed-Signal Circuits

    Author : Erik Backenius; Mark Vesterbacka; Kejll O. Jeppson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mixed-signal; Substrate noise; Substrate modeling; Simultaneous switching noise; SSN; Digital; Analog; Clock; Electronics; Elektronik;

    Abstract : In many consumer products, e.g., cellular phones and handheld computers, both digital and analog circuits are required. Nowadays, it is possible to implement a large subsystem or even a complete system, that earlier required several chips, on a single chip. READ MORE

  6. 4. On Reduction of Substrate Noise in Mixed-Signal Circuits

    Author : Erik Backenius; Mark Vesterbacka; Jan-Erik Eklund; Linköpings universitet; []
