  • Modeling and Design of Interconnects and Passive Components for Millimeter-Wave Integrated Circuits in Silicon

    Creator:
    Zheng, Lei
    Abstract:
    For mmWave Integrated Circuit (IC) design, co-integration of passives can reduce size and power consumption, increase reliability, and reduce overall cost. However, skin and proximity effects in the metallization are aggravated at mmWave frequencies, resulting in increased attenuation and degradation of overall performance. Furthermore, tight integration of passive components (to...

  • Analysis and modeling of monolithic on-chip transformers on silicon substrates

    Creator:
    Mayevskiy, Yevgeniy
    Abstract:
    Passive components, including spiral inductors and transformers, fabricated on silicon-based substrates are placing an increasing demand on radio-frequency integrated circuit (RFIC) design. Performance of the RFIC suffers from several non-ideal effects that must be taken into account in order to create a successful design. In particular, monolithic transformers can be...

  • Design of Compact Passive Components and Circuits for RF and Millimeter-Wave Integrated Circuit in Silicon

    Creator:
    Dong, Xuanyi
    Abstract:
    Emerging fifth generation (5G) and beyond 5G communication networks are stimulating the design of radio-frequency (RF) and millimeter-wave (mmWave) integrated circuits for wireless transceivers systems. While co-integration of active circuits and diverse passive components becomes feasible at these high operating frequencies, circuit design is faced with significant challenges due to...

  • An Interactive Tool for Teaching Transmission Line Concepts

    Creator:
    Scheible, Keaton
    Abstract:
    In college transmission lines courses, students are expected to understand how different circuit configurations affect the signals on a transmission line. Having a way to visualize these signals can greatly improve their learning experience. This thesis details the development of an open source, interactive learning tool used to illustrate fundamental...

  • Analysis and modeling of multi-mode effects in coplanar waveguide bends

    Creator:
    Senguttuvan, Rajarajan
    Abstract:
    A novel method for modeling bends in coplanar waveguides (CPWs) is described. The CPW can be viewed as a pair of parallel coupled quasi-slot lines. Bends in the CPW are modeled as a non-uniform coupled line system in terms of their even- and odd- mode characteristics. This modeling approach is...

  • Equivalent circuit modeling of on-chip magnetic devices based on terminal measurements

    Creator:
    Gaskill, Steven G.
    Abstract:
    The addition of thin-film alloy magnetic materials to integrated circuit processing enables a number of novel monolithic circuits. Examples include fully integrated magnetic field sensors, signal and power galvanic isolation circuits, and power supplies on chip (PwrSoC). There are several benefits to integrating these traditionally off-chip devices, including improved manufacturability,...

  • Enabling metal-fill-aware design of integrated circuits

    Creator:
    Shilimkar, Vikas S.
    Abstract:
    In advanced integrated circuit (IC) processes, the metal fill inserted to meet foundry imposed density requirements degrades the performance of interconnects and passive components which ultimately affects the overall circuit performance. Accounting for this degradation through electromagnetic and equivalent circuit modeling is becoming a critical aspect of IC design. However,...
