0.42 THz Transmitter with Dielectric Resonator Array Antenna
(University of Waterloo, 2019-07-23)Off chip antennas do not occupy the expensive die area, as there is no limitation on their building material, and can be built in any size and shape to match the system requirements, which are all in contrast to on-chip ... -
60 Watts Broadband Push Pull RF Power Amplifier Using LTCC Technology
(University of Waterloo, 2013-09-27)The continuous increase in wireless usage forces an immense pressure on wireless communication in terms of increased demand and spectrum scarcity. Service providers for communication services had no choice but to allocate ... -
Design and Implementation of Calculated Readout by Spectral Parallelism (CRISP) in Magnetic Resonance Imaging (MRI)
(University of Waterloo, 2010-05-20)CRISP is a data acquisition and image reconstruction technique that offers theoretical increases in signal-to-noise ratio (SNR) and dynamic range over traditional methods in magnetic resonance imaging (MRI). The incoming ... -
Magnetic Transduction for RF Micromechanical Filters
(University of Waterloo, 2012-02-27)The use of electrostatic transduction has enabled high-Q miniaturized mechanical resonators made of non-piezoelectric material that vibrate at high and ultra high frequencies. However, this transduction technique suffers ... -
