  • 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...

  • A high-swing class-AB CMOS operational amplifier

    Creator:
    Yu, Choung
    Abstract:
    A high-swing, high-linearity Class-AB CMOS operational amplifier suitable for high speed application is presented. It does not exhibit large-signal slewing effects as do others; its output current is limited by MOSFET aspect ratios and the total power supply voltage. A rail-to-rail common-mode input range is achieved by a topology which...

  • A chopper-stablized CMOS operational amplifier

    Creator:
    Ann, Seung-Han
    Abstract:
    The chopper-stabilized operational amplifier has good low frequency noise properties. Unfortunately a simple technique for simulation of the chopper-stabilized operational amplifier has not been available. This thesis describes the implementation of a differential amplifier using chopper stabilization and its circuit modeling for the SPICE simulation. This circuit has been designed...

  • 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...

  • A high-swing CMOS operational amplifier topology

    Creator:
    Yang, John Jian
    Abstract:
    A circuit topology for high-swing, high-linearity CMOS operational amplifiers has been developed. The technique uses parallel-connected p- and n-channel input pairs to realize an input common-mode voltage range nearly equal to the total power supply voltage. High linearity is achieved by summing the DC bias and AC small-signal currents so...

  • Current mode analog and digital circuit design

    Creator:
    Liang, Guojin
    Abstract:
    In this dissertation, two important current mode circuit design subjects have been explored. In the first part, the switched-current circuit technique has been investigated. The fundamental performance and limitations of this technique are explored. One of the major limitations, the signal distortion caused by clock feedthrough has been substantially reduced...

  • A time-multiplexed switched-capacitor circuit for neural network applications

    Creator:
    Hansen, James Edward, 1962-
    Abstract:
    Analog computation in the form of neural networks is currently receiving much attention. Existing algorithms cannot be easily implemented in hardware because of the large number of neurons needed and the number of connections necessary between them. These problems have motivated development of alternatives to a conventional implementation. Hence, a...

  • Operational amplifier compensation using doublet-decompression for switched-capacitor circuits

    Creator:
    Jen, Shin D.
    Abstract:
    A frequency compensation technique for increasing the settling speed of two-stage operational amplifiers used in switched-capacitor applications has been developed. By properly decompressing the pole-zero doublet to form a three-pole one zero system, the settling speed is increased up to 50 percent as compared to the optimized two-pole system.
