  • A fast-settling folded-cascode CMOS operational amplifier

    Creator:
    Abu-Dayeh, Mahmoud A.
    Abstract:
    A fast-settling CMOS operational amplifier using the folded-cascode topology has been designed. The design is based on a theory developed by Yang et al for the optimum settling time of two-pole systems for switched-capacitor applications. The theory states that the two poles are separated by a given factor in order...

  • Data-structure builder for VLSI/CAD software

    Creator:
    Eum, Doo-hun
    Abstract:
    Relational database systems have successfully solved many business data processing problems. The primary reason of this success is that the relational data model provides a simple, yet flexible view of data as tables. In studying VLSI/CAD data, we noticed that they are often represented in formats similar to relational tuples....

  • Program allocation for hypercube based dataflow systems

    Creator:
    Freytag, Vincent R.
    Abstract:
    The dataflow model of computation differs from the traditional control-flow model of computation in that it does not utilize a program counter to sequence instructions in a program. Instead, the execution of instructions is based solely on the availability of their operands. Thus, an instruction is executed in a dataflow...

  • A programmable BiCMOS transconductance-capacitor filter for high frequencies

    Creator:
    Beck, Jeffery S.
    Abstract:
    With advancements in CMOS technology, high speed analog circuits that were traditionally implemented with discrete circuit components can now be made monolithically. Antialiasing filters for video signals as well as signal conditioning filters in high speed communication channels are examples of applications where high frequency integrated circuits are now feasible....

  • MOSFET-only predictive track and hold circuit

    Creator:
    Qiu, Xiangping
    Abstract:
    High-accuracy and high-speed CMOS track-and-hold (T/H) or sample-and-hold (S/H) circuits are an important part of the analog-to-digital interface. The switched-capacitor (SC) circuits usually contain one or more op-amps whose dc offset, finite gain, finite bandwidth have a big impact on the accuracy of the track-and-hold circuit. Basic correlated double sampling...

  • Design of high-speed adaptive parallel multi-level decision feedback equalizer

    Creator:
    Xiang, Yihai
    Abstract:
    Multi-level decision feedback equalization (MDFE) is an effective technique to remove inter-symbol interference (ISI) from disk readback signals, which uses the simple architecture of decision feedback equalization. Parallelism which doubles the symbol rate can be realized by setting the first tap of the feedback filter to zero. A mixed-signal implementation...

  • Design of high-speed summing circuitry and comparator for adaptive parallel multi-level decision feedback equalization

    Creator:
    Gao, Hairong
    Abstract:
    Multi-level decision feedback equalization (MDFE) is an effective sampled signal processing technique to remove inter-symbol interference (ISI) from disk read-back signals. Parallelism which doubles the symbol rate can be realized by utilizing the characteristic of channel response and decision feedback equalization algorithm. A mixed-signal IC implementation has been chosen for...

  • Analysis and design of bandpass delta-sigma A/D converters

    Creator:
    Zhai, Dalun
    Abstract:
    A new approach to oversampled delta-sigma A/D converters ( AZ modulators ) is introduced, where a differential pseudo-Npath filter stage is used as a basic cell. In this band-pass application, the z to -zN transformation is employed to realize a RAM-type pseudo-2-path lossless integrator. The bandpass second-order and 4th-order delta-sigma...
