  • Distortion analysis of switched-current circuits

    Creator:
    Lee, Wing-sun R.
    Abstract:
    Recently, switched-current circuits have received great attention because they offer potentially better performance in terms of speed, low voltage power supplies, and accuracy in mixed-mode analog-digital signal processing. In this thesis, the distortion characteristics, DC offset and AC gain errors induced by the threshold voltage, channel width, channel length, and...

  • A CMOS differential line driver

    Creator:
    Jiang, William
    Abstract:
    A short-circuit-protected line-driver circuit is particularly adapted for use in a CMOS differential line-driver system, where one line-driver circuit provides a true output signal, and another line-driver circuit provides a complementary false output signal. A short-circuit is sensed by measuring current through a secondary pull-up transistor, and disabling a primary...

  • CMOS analog design using a digital gate array

    Creator:
    Liu, Tian-chen
    Abstract:
    The core area of a conventional CMOS digital gate array consists of only one size of NMOS device and one size of PMOS device. Both primitives have fixed minimum channel lengths, and this has significantly impeded analog applications. This work has shown that by forming series and parallel interconnections between...

  • 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.

  • 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...

    Creator:
    Herpe, Joachim
    Abstract:
    Lipids, especially phospholipids, are very common but important molecules found in cells and animal tissue, performing many biological functions, particularly in membranes. Lipids, when mixed with water, spontaneously form ordered systems, such as micelles, vesicles and multibilayers. The size of these systems and their degree of ordering depend on the...

  • Analytical model of GaAs MESFET output conductance with frequency and temperature dependent parameters

    Creator:
    Lam, Steven C. F.
    Abstract:
    The output characteristics of a conventional GaAs depletion-mode MESFET device have been investigated. One of the important parameters of the small-signal GaAs MESFET model, g[subscript ds] (output conductance), is shown to be frequency and temperature dependent. Variations in g[subscript ds] are a serious problem in many analog and digital circuits...

  • A CAD noise model for chopper-stabilized switched-capacitor filters

    Creator:
    Shenoy, Ravindra Umanath
    Abstract:
    A modeling technique for simulating the noise performance of chopper-stabilized switched-capacitor filters using SPICE2 is presented. A method for selection of switched-capacitor network (SCN) stages to be chopped and an op amp topology for low noise applications are also outlined. Validity of the modeling is verified by the close agreement...
