  • 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...

  • Analysis and design of CMOS RF LNAs with ESD protection

    Creator:
    Chandrasekhar, Vinay
    Abstract:
    An analysis that accounts for the effect of standard electrostatic discharge (ESD) structures on critical LNA specifications of noise figure, input matching and gain is presented. It is shown that the ESD structures degrade LNA performance particularly for higher frequency applications. Two LNAs, one with ESD protection and one without,...

  • Ring amplification for switched capacitor circuits

    Creator:
    Hershberg, Benjamin Poris
    Abstract:
    A comprehensive and scalable solution for high-performance switched capacitor amplification is presented. Central to this discussion is the concept of ring amplification. A ring amplifier is a small modular amplifier derived from a ring oscillator that naturally embodies all the essential elements of scalability. It can amplify with accurate rail-to-rail...

  • 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.

  • Thin-film wideband tunnel-diode amplifier

    Creator:
    Hsieh, Edmund Jui-ching
    Abstract:
    Wideband tunnel-diode amplifiers using common-base transistor stages for isolation were investigated for stability criteria, frequency response, and the effects of temperature and voltage supply fluctuations. For the first time the full frequency spectrum of a tunnel-diode, from d-c to the gigahertz (GHz) range, was able to be utilized in an...

  • Active network synthesis using operational amplifiers

    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...

  • 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...
