  • 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...

  • Current mode analog and digital circuit design

    Creator:
    Liang, Guojin
    Abstract:
    In this dissertation, two important current mode circuit design subjects have been explored. In the first part, the switched-current circuit technique has been investigated. The fundamental performance and limitations of this technique are explored. One of the major limitations, the signal distortion caused by clock feedthrough has been substantially reduced...

  • A circuit design to generate and maintain a constant magnetic flux

    Creator:
    Tuntawiroon, Chalermchai
    Abstract:
    A circuit designed to generate and maintain a constant magnetic flux is presented by using a sample-data control system, instead of a continuous control system. A Hall generator is used as the magnetic sensing element, and is operated with a pulse bias to allow a large output. The output of...

  • 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...

  • Design techniques for clocking high performance signaling systems

    Creator:
    Hanumolu, Pavan Kumar
    Abstract:
    Scaling of CMOS technology has progressed relentlessly for the past several decades. In order for this unprecedented scaling to benefit the performance of large digital systems, the communication bandwidth between integrated circuits (ICs) must scale accordingly. However, interconnect technology does not scale as aggressively, making communication between chips the major...

  • Component to multi-track feeder assignment and board sequencing for printed circuit board assembly

    Creator:
    Li, Yu-An
    Abstract:
    This research was motivated by the use of multi-track feeders in the printed circuit board (PCB) assembly. In a low volume, high mix production environment, setup time is usually considered more important than processing time. Implementation of multi-track feeders not only increases the capacity of the surface mount machines but...

  • Low noise FSCL digital circuits for decimation filter

    Creator:
    Wong, Man Wa
    Abstract:
    A new circuit technique called Folded Source Coupled Logic (FSCL) has been developed to implement the digital section of mixed-signal IC applications. This FSCL circuit technique offers the advantage of low overlap current spikes during the switching transitions of conventional CMOS gates. This overlap current spike has become one of...

  • Fully-differential current-mode CMOS circuits and applications

    Creator:
    Zele, Rajesh H.
    Abstract:
    With increasing interest in current-mode analogue processing due to its high performance properties such as speed, bandwidth and accuracy compared to voltage-mode processing, new current-mode alternatives to various conventional circuit designs are appearing. In this report, a novel circuit design to construct a fully-differential current-mode operational amplifier ( OP-AMP )...
