  • A comparison of substrate noise coupling in lightly and heavily doped CMOS processes for 2.4 GHz LNA's

    Creator:
    Hazenboom, Duncan S.
    Abstract:
    Three types of low noise amplifiers operating at 2.4GHz were designed. They are the commonly used single-ended and differential amplifiers as well as a new quasi-differential amplifier. The substrate noise injected into these amplifiers is examined for both heavily and lightly doped CMOS substrates. For the single-ended amplifier the noise...

  • A charge sensitive amplifier for use with piezoelectric transducers

    Creator:
    Magnuson, Waldo George, Jr.
    Abstract:
    The design of a preamplifier for use with a piezoelectric transducer is generally approached from the point of view that an extremely high input impedance is required to obtain low frequency response. However, piezoelectric transducers are essentially charge generators and this fact may be utilized in designing preamplifiers to be...

  • Design of high-input impedance, wideband transistorized amplifiers

    Creator:
    Huaccho Salazar, Reynaldo
    Abstract:
    Conventional bi-polar transistors are inherently low input impedance devices. Transistor amplifiers have been designed which will present high input impedance, but the frequency response is limited to low frequencies, hundreds of kilocycles. This thesis investigates both field effect transistors and positive feedback as applied to high input impedance wide band...

  • Dynamic biasing for ring amplification

    Creator:
    Farahbakhshian, Farshad
    Abstract:
    New amplifier architectures are presented using non-traditional methods of biasing. Time-based dynamic biasing and signal-based dynamic biasing are discussed in the context of new architectures. This includes a new form of ring amplification with a dynamic deadzone, allowing for a structure whose coarse path does not consume static power.

  • Feedforward noise cancellation techniques

    Creator:
    Yang, Bangda
    Abstract:
    Supply noise is one of the major considerations in almost all analog building blocks. In the past, adequate supply rejection is usually achieved with circuit isolation or excess capacitive coupling. However, this brute force method requires large silicon area and degrades feedback bandwidth. In this study, a method of enhancing...

    Creator:
    Chiang, Ching Hwa
    Abstract:
    Three synthesis methods for the realization of the voltage transfer function by means of RC elements and three different active devices are presented. These three devices are a high-gain amplifier, a voltage controlled voltage source (VCVS) and a negative immittance converter (NIC). The VCVS and NIC as well as the...

  • Two-integrator detector for known-signal-in-noise identification

    Creator:
    Albright, Robert James
    Abstract:
    This thesis discusses the design and evaluation of an instrument that can detect known signals in noise. This detector uses two integrators to sense a difference in the received signal between half-cycles of the known signal. The detector is useful for sensing signals in the approximate frequency range of 100...

  • A lock-in amplifier for detecting weak signals buried in noise

    Creator:
    Clinton, Ted Warner
    Abstract:
    It is often necessary in communication systems to detect very small signals that are buried in noise. One device used to accomplish this is a lock-in amplifier. Initially the theory of operation is considered. Then the circuit design of a low cost lock-in amplifier is given. The amplifier, employing linear...

  • A test fixture and deembedding procedure for high-frequency substrate characterization

    Creator:
    Webb, Kyle M.
    Abstract:
    At frequencies exceeding 1-2 GHz, the substrate network models used in substrate coupling simulation must account for the reactive nature of the substrate. Unlike at low frequencies, where the purely resistive substrate models can be validated through DC resistance measurements, these high-frequency models, comprising reactive components, must be validated through...

  • A comparison of substrate noise coupling in heavily doped and lightly doped substrates for mixed-signal circuits

    Creator:
    Ayers, James S.
    Abstract:
    An analysis of substrate noise coupling in mixed-signal circuits has been performed in the TSMC 0.25 [mu]m lightly doped and heavily doped CMOS processes. Methods to minimize noise coupling in both the chip design and board design phases are presented along with techniques for accurate circuit simulation of noise coupling....
