  • Current-feedthrough cancellation technique for current-mode T/H circuits

    Creator:
    Young, David Y. W.
    Abstract:
    In this paper, an analysis of the clock-feedthrough effects in switched-current (SI)' circuits will be presented. The clock-feedthrough effects caused by the non-ideal characteristic of MOS switches when they are turned off limit the accuracy of the analog track-and-hold (T/H) circuits. A model to analyze and characterize this effect is...

  • CMOS low noise amplifier design utilizing monolithic transformers

    Creator:
    Zhou, Jianjun J.
    Abstract:
    Full integration of CMOS low noise amplifiers (LNA) presents a challenge for low cost CMOS receiver systems. A critical problem faced in the design of an RF CMOS LNA is the inaccurate high-frequency noise model of the MOSFET implemented in circuit simulators such as SPICE. Silicon-based monolithic inductors are another...

  • 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...

  • Design and computer aided optimization of a fully integrated CMOS RF distributed amplifier

    Creator:
    Ballweber, Brian M.
    Abstract:
    Advancements in the sophistication and complexity of modern electronic systems are creating a need for highly integrated systems with ever higher operational frequencies. The economical demands of these systems dictate that they be implemented using low cost fabrication technologies, such as digital CMOS. One of the major challenges facing circuit...

  • MOS switched-current biquadratic filters

    Creator:
    Lee, Bor
    Abstract:
    A MOS biquadratic (biquad) filter employing the switched-current technique is reported. The circuit uses current-mode processing which can offer wide bandwidth, low voltage operation, and can be implemented with standard CMOS technology. Examples of lowpass, highpass, and bandpass filters are given which illustrate the synthesis procedures and the versatility of...

  • A Fully Integrated Bio-potential Low-noise Amplifier Utilizing Capacitor Multipliers

    Creator:
    Yong, OnnLim
    Abstract:
    In any biomedical signal acquisition system, a front-end amplifier is needed to amplify low amplitude bio-signals while filtering out any unwanted low-frequency artifacts. The design of low frequency poles within the sub-Hz range implies very large time-constants which goes against system integrability. In recent years, the pseudo resistor has been...

  • Switch-capacitor Power Amplifier with Enhanced Power Back-off Efficiency and Linearity

    Creator:
    Qiao, Bo
    Abstract:
    Nowadays, wireless communication systems use high-order quadrature amplitude modulation (QAM) together with orthogonal frequency-division multiplexing (OFDM) to increase the link capacity and robustness. These signals always have large peak-to-average power ratio (PAPR) and require power amplifiers (PAs) achieve both high efficiency and linearity simultaneously. For the efficiency, the complementary metal...
