  • 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...

  • Design techniques of high-performance switched capacitor circuits in the presence of component imperfections

    Creator:
    Huang, Yunteng
    Abstract:
    This thesis describes design techniques for high-performance switched-capacitor (SC) circuits, primarily for high-linearity low-noise SC circuits in the presence of component imperfections, such as nonlinear op-amp voltage transfer characteristics, capacitor nonlinearities as well as the finite op-amp dc gain and op-amp offset and noise. Various correlated-double-sampling (CDS) schemes are discussed,...

  • High-speed switched-capacitor filters based on unity-gain buffers

    Creator:
    Bruneau, David
    Abstract:
    In this work a new voltage buffer, the drain-follower, achieves 300MHz band-width with 2pF load, a dc gain of 0.993V/V, 1mV offset voltage, -60 dB total harmonic distortion at 1.4Vpp output voltage and 6.5mW power dissipation from 5V supply. A unity-gain buffer switched-capacitor biquad filter has been implemented in 0.5μm...

  • 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.

  • Analysis and measurement of charge injection in switched-capacitor circuits

    Creator:
    Shen, Min
    Abstract:
    It has been verified by theoretical analysis, circuit simulation and test that two switch transistors in parallel in a simple sample and hold circuit can be achieve high speed with low error voltage due to charge injection. The wide transistor provides low RC time constant when it is closed and...

  • An efficient switched capacitor buck-boost voltage regulator using delta-sigma control loop

    Creator:
    Rao, Arun
    Abstract:
    Voltage converters or charge pumps find their use in many circuits. They are extensively used in hand held devices as cell phones, pagers, PDA's and laptops. Some of the important issues relating to design of voltage regulators for handheld devices are size, efficiency and noise. Another important factor to be...

  • 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...

  • Digitally-programmable switched-current filters

    Creator:
    Yesilyurt, Ayse Gul
    Abstract:
    Digitally-programmable filters have been an ongoing research topic for a number of years. The first such filters were FIR transversal filters using Charge-Coupled Devices (CCD's) and IIR recursive filters using switched-capacitor (SC) techniques. Although both techniques achieve excellent results, they require non-standard and/or additional IC fabrication steps. Low substrate doping...

  • 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...
