Abstract:
This work addresses neural and analog computation on reconfigurable mixed-signal platforms. Many engineered systems could gain tremendous benefits by emulating neural systems. For example, neural systems are incredibly power efficient and fault-tolerant. They are also capable of types of computation that we cannot yet match with conventional computers. Neuromorphic engineers typically implement neural computation using analog circuits because they are low-power and naturally model some aspects of neurobiology. One problem with analog circuits is that they are typically inflexible. To address t

Abstract:
This body of work as whole has the theme of using floating-gates and reconfigurable systems to explore and implement non-traditional computing solutions to difficult problems. Various computational methodologies are used simultaneously to solve problems by mapping pieces of them to the appropriate type of computer. There exists no systematic approach to simultaneously apply analog, digital, and neuromorphic techniques to solving general problems. Typically, this is a very difficult task, and one that few attempt to undertake. However, when done right, solutions can be found with orders-of-magn

The purpose of this research is to create a solid framework for embedded system design with field-programmable analog arrays (FPAAs). To achieve this goal, we've created a unified approach to the three phases of FPAA system design: (1) the hardware architecture; (2) the circuit design and modeling; and (3) the high-level software tools. First, we describe innovations to the reconfigurable analog hardware that enable advanced signal processing and integration into embedded systems. We introduce the multiple-input translinear element (MITE) FPAA and the dynamically-reconfigurable RASP 2.9v FPAA,

FFT-based tests (e.g. gain, distortion, SNR, etc.) from a device-under-test (DUT) exhibit normal distributions when the measurement is repeated many times.

Abstract:
High-speed and high-resolution digital-to-analog converters (DACs) are vital components in all telecommunication systems. Radio-frequency digital-to-analog converter (RFDAC) provides high-speed and high-resolution conversion from digital domain to an analog signal. RFDACs can be employed in direct-conversion radio transmitter architectures. The idea of RFDAC is to utilize an oscillatory pulse-amplitude modulation instead of the conventional zero-order hold pulse amplitude modulation, which results in DAC output spectrum to have high energy high-frequency lobe, other than the Nyquist main lobe.

The key feature of the batch-based tracker is an image template-matching approach that handles data association and clutter in measurements.

Abstract:
Η ενσωμάτωση των κωδίκων Turbo σε ένα ευρύ φάσμα εφαρμογών λόγω της εκπληκτικής αποδόσεώς τους που προσεγγίζει το θεμελιώδες όριο του Shannon, απαιτεί αποδοτικές αρχιτεκτονικές και υλοποιήσεις υψηλού ρυθμού διεκπεραίωσης και χαμηλής κατανάλωσης ενέργειας όσον αφορά την εξαιρετικά πολύπλοκη και χρονοβόρα επαναληπτική αποκωδικοποίησή τους. Η παρούσα διδακτορική διατριβή μελετά την χρήση της τεχνολογίας Πυριτίου-Γερμανίου (SiGe) BiCMOS σε αναλογικές αρχιτεκτονικές για την υλοποίηση αποκωδικοποιητών Turbo υψηλού ρυθμού διεκπεραίωσης και όσο το δυνατόν χαμηλής κατανάλωσης ισχύος.
