  • A direct-conversion offset-cancellation mixer in 2.4 GHz CMOS

    Creator:
    Lehne, Mark A.
    Abstract:
    We present a new circuit design for adaptive offset cancellation in a fully differential 2.4 GHz CMOS direct conversion mixer. Our circuit structure is a modification of a Gilbert cell mixer in which offsets are cancelled by injecting cancellation currents into the legs of the mixer by dynamically varying the...

  • Design of an asynchronous third-order finite impulse response filter

    Creator:
    Oren, Joel A.
    Abstract:
    With the increased demand for complex digital signal processing systems, real-time signal processing requires higher throughput systems. In the past, the throughput has been increased by increasing the clock rates, but synchronization can become increasingly more difficult. Recently there has been renewed interest in designing asynchronous digital systems. In an...

  • Analysis and simulation of a variable speed induction motor

    Creator:
    Haskins, Raymond A.
    Abstract:
    A model of a squirrel cage induction machine, d.c.- link power supply and centrifugal pump is developed and used in the design and evaluation of a perturbation feedback control system for a sewage pumping station. A comparison of the simulation model of the induction machine and a laboratory machine to...

  • 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...

  • A universal CMOS current-mode operational amplifier

    Creator:
    Botelho, Cindy
    Abstract:
    It has become customary in electrical engineering to think of signal processing in terms of voltage variables to the exclusion of current variables. This tendency has resulted in voltage signal processing circuits such as voltage-controlled voltage sources (VCVS) and voltage-mode operational amplifiers. However, the VCVS operational amplifier has several limitations...

  • A performance study of multithreading

    Creator:
    Kwak, Hantak
    Abstract:
    As the performance gap between processor and memory grows, memory latency will be a major bottleneck in achieving high processor utilization. Multithreading has emerged as one of the most promising and exciting techniques used to tolerate memory latency by exploiting thread-level parallelism. The question however remains as to how effective...

  • A multi-microprocessor debug executive

    Creator:
    Edmonds, Douglas E.
    Abstract:
    The system in this thesis uses multiple Intel iSBC86/12A cards connected to the Intel Multibus. The system was written using the Intel language PLM86. The final result is a low level debug tool that provides the user with the following capabilities: examine/change memory, examine/change processor registers, load a user written...

  • Embedded passives in a multilayer medium

    Creator:
    Seo, Yongseok, 1958-
    Abstract:
    Recent advances in high density low cost RF and microwave three dimensional integration technologies using LTCC(Low Temperature Cofired Ceramics), laminate and other multilayer hybrid and integrated circuits have increased interest in the design of embedded passive components such as inductors, capacitors and filters. The purpose of this study is to...

  • The analysis and design of a broadband microwave buffer amplifier

    Creator:
    Dunsmore, Joel P.
    Abstract:
    In microwave network analysis, proper matching of the measurement system is necessary to prevent measurement errors and provide a proper terminating impedance for the device-under-test. To obtain this matching, a buffer amplifier is often used in the first stage of the network analyzer. This study describes the design and analysis...

  • 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...
