Controlling And Processing Core For Wireless Implantable Telemetry System, Naeeme Modir
Electronic Thesis and Dissertation Repository
Wireless implantable telemetry systems are suitable choices for monitoring various physiological parameters such as blood pressure and volume. These systems typically compose of an internal device implanted into a living body captures the physiological data and sends them to an external base station located outside of the body for further processing. The internal device usually consists of a sensor interface to convert the collected data to electrical signals; a digital core to digitize the analog signals, process them and prepare them for transmission; an RF front-end to transmit the data outside the body and to receive the required commands from …

A significant problem for space-based systems is multipactor - an avalanche of electrons caused by repeated secondary electron emission (SEE). The consequences of multipactor range from altering the operation of radio frequency (RF) devices to permanent device damage. Existing efforts to suppress multipactor rely heavily on limiting power levels below a multipactor threshold [1]. This research applies surface micromachining techniques to create porous surfaces to control the secondary electron yield (SEY) of a material for multipactor suppression. Surface characteristics of interest include pore aspect ratio and density. A discussion is provided on the advantage of using electroplating (vice etching) to …

Data centers (DCs) is becoming increasingly an integral part of the computing infrastructures of most enterprises. Therefore, the concept of DC networks (DCNs) is receiving an increased attention in the network research community. Most DCNs deployed today can be classified as wired DCNs as copper and optical fiber cables are used for intra- and inter-rack connections in the network. Despite recent advances, wired DCNs face two inevitable problems; cabling complexity and hotspots. To address these problems, recent research works suggest the incorporation of wireless communication technology into DCNs. Wireless links can be used to either augment conventional wired DCNs, or …

A 38 Ghz On-Chip Antenna In 28-Nm Cmos Using Artificial Magnetic Conductor For 5g Wireless Systems, Max Ammann
Conference papers
This paper presents the first-ever millimeter wave on-chip antenna (AoC) in 28 nm CMOS technology. The addition of artificial magnetic conductor (AMC) can increase the antenna's power gain and radiation efficiency to -1.75 dBi and 22%, respectively, with an occupied area of 0.95 mm×4.75 mm at 38 GHz. This structure is intended for fully integrated single-chip nanometer CMOS transceivers for 5G communication systems.

In this thesis, the various kinds of Class-F radio frequency power amplifiers are discussed. The Class-F3 RFPA is the one which has been designed and analyzed. It consists of an RF choke, blocking capacitor and a loading network. The loading network consists of a tank circuit resonating at fundamental operating frequency and also a parallel resonator circuit tuned to third harmonic. For a better understanding of the operation of Class-F3 amplifier, we go back to Class-C amplifier and discuss it briefly. Here the design remains same, operating at conduction angles less than 180 degree. The design equations were used to …
