Embedded passives in a multilayer mediumSeo, Yongseok, 1958- 15 July 1997 (has links)
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 develop the design methodology of multilayer
components such as coupled line filters in a multilevel inhomogeneous medium. Although
multilayer assembly including simple components have been used in the past
for digital and low frequency systems, RF and microwave circuits have been fabricated
mostly in single level configurations. The use of multilayer three dimensional
components and circuits makes microwave circuits more compact and the design
more flexible.
This thesis describes the basic principles and computational procedure for
the design of multilayer components such as, planar single and two-level spirals for
applications as an inductive elements for RF and MICs, and coupled line band-pass
filter circuits consisting of multiple sections. It is shown that both the quality factor
and the inductance values can be enhanced by using multilevel spirals. Design methodology for general multisection filter consisting of asymmetric and multiple
coupled lines is formulated and presented. It is shown that given the filter specifications,
e.g., bandwidth, selectivity, input and output impedances, single, two and
multilevel coupled line filters can be physically realized.
The design procedure for narrow band filters is formulated in the conventional
manner by using the equivalent circuit with admittance inverters and the component
values of the low-pass prototype for Butterworth, Chebyshev and other response
functions. Examples of Butterworth and Chebyshev multisection filters are included
to demonstrate the design procedure.
The physical multilevel filter is then optimized by using the SPICE model
for coupled multiconductor lines on commercial CAD tool like LIBRA. The optimized
multilevel structure design has been validated by MOMENTUM commercial
electromagnetic simulator tool. The design methodology is validated by comparing
the theoretical results with measurement data for a strip line filter fabricated on
FR-4. / Graduation date: 1998

High frequency and high dynamic range continuous time filtersLewinski Komincz, Artur Juliusz 17 September 2007 (has links)
Many modern communication systems use orthogonal frequency division
multiplexing (OFDM) and discrete multi-tone (DMT) as modulation schemes where
high data rates are transmitted over a wide frequency band in multiple orthogonal subcarriers.
Due to the many advantages, such as flexibility, good noise immunity and the
ability to be optimized for medium conditions, the use of DMT and OFDM can be found
in digital video broadcasting, local area wireless network (IEEE 802.11a), asymmetric
digital subscriber line (ADSL), very high bit rate DSL (VDSL) and power line
communications (PLC). However, a major challenge is the design of the analog frontend;
for these systems a large dynamic range is required due to the significant peak to
average ratio of the resulting signals. In receivers, very demanding high-performance
analog filters are typically used to block interferers and provide anti-aliasing before the
subsequent analog to digital conversion stage. For frequencies higher than 10MHz, Gm-C filter implementations are generally
preferred due to the more efficient operation of wide-band operational transconductance
amplifiers (OTA). Nevertheless, the inherent low-linearity of open-loop operated OTA
limits the dynamic range. In this dissertation, three different proposed OTA linearity
enhancement techniques for the design of high frequency and high dynamic range are
presented. The techniques are applied to two filter implementations: a 20MHz second
order tunable filter and a 30MHz fifth order elliptical low-pass filter. Simulation and
experimental results show a spurious free dynamic range (SFDR) of 65dB with a power
consumption of 85mW. In a figure of merit where SFDR is normalized to the power
consumption, this filter is 6dB above the trend-line of recently reported continuous time
filters.
