  • 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....

  • High speed buffers for op-amp characterization

    Creator:
    Rangan, Giri N. K.
    Abstract:
    The feasibility of developing test circuits to perform in-circuit testing of analog circuits is investigated in this thesis. A modular approach to analog testing has been adopted. Accordingly, the testing of an operational amplifier, which is a basic building block in analog circuits, is addressed. One convenient technique for measuring...

  • Opamp characterization techniques

    Creator:
    Ramamurthy, Karthik
    Abstract:
    Standard methodologies exist for testing and characterizing digital circuits but the same cannot be said of analog circuits. Though much theoretical work has been done to model the linear and nonlinear aspects of analog circuits, a firm practical background for the design of testable analog cells has yet to be...

  • An adaptive all-pass filter for decision feedback equalization

    Creator:
    Wiedmann, Ralf
    Abstract:
    Increasing densities on magnetic data storage devices leads to problems of severe intersymbol interference (ISI), additive noise and non-linearities. Advanced detection strategies for magnetic recording channels fall into two categories: partial response equalization with maximum likelihood decoding and decision feedback equalization. This study focuses on doing an adaptive all-pass forward...

  • Equalizer design for MDFE channels using nonlinear optimization

    Creator:
    Onu, Dan
    Abstract:
    Decision feedback equalization (DFE) is a sampled-data technique used for data recovery in digital communications channels. Multi-level decision feedback equalization (MDFE) has been developed for channels using the 2/3(1,7) RLL code. The optimum detector for a digital communication channel affected by ISI and noise consists of a matched filter, followed...

  • A DAC and comparator for a 100MHz decision feedback equalization loop

    Creator:
    Engelbrecht, Linda M.
    Abstract:
    Decision Feedback Equalization (DFE) in a data recovery channel filters the bit decision in the current symbol period in generating the sample at the comparator in the subsequent clock period. The operations of sampling, comparing, filtering the decision bits into a feedback signal, and subtraction of that feedback signal are...

  • Optimum quantization for the adaptive loops in MDFE

    Creator:
    Parthasarathy, Priya
    Abstract:
    Multi-level decision feedback equalization (MDFE) is a sampled signal processing technique for data recovery from magnetic recording channels which use the 2/3(1,7) run length limited code. The key adaptive feedback loops in MDFE are those which perform the timing recovery, gain recovery, dc offset detection, and adaptive equalization of the...

  • Device characterization and analog circuit design for heterojunction FETs

    Creator:
    Wang, Binan
    Abstract:
    Present day data processing technology requires very high speed signal processing and data conversion rates. Traditionally, these circuits have been implemented in silicon MOS technology, whose high speed performance is limited, due to inherent material properties. Though relatively immature compared to silicon technology, GaAs integrated circuit technology appears to be...

  • Novel switched-capacitor circuits for delta-sigma modulators

    Creator:
    Yesilyurt, Ayse Gul
    Abstract:
    Oversampled delta-sigma modulation is one of the widely used A/D conversion techniques for narrow bandwidth signals. In this study several new lowpass and bandpass delta-sigma modulator architectures as well as novel pseudo-N-path integrators that can be used in implementing these architectures are proposed. By using multiplexing techniques the new lowpass...
