MODELING OF FINFET DEVICES AT CRYOGENIC TEMPERATURES

Cryogenic operation of advanced CMOS is fundamental for scalable quantum computing interfaces and cryogenic RF electronics, yet prevailing device models inadequately capture transistor behaviour far below ambient temperature. This thesis presents an empirical compact modeling framework for FinFET devices that extends the well-established Angelov model formulation at room temperature to accurately reproduce DC drain current characteristics from ambient down to cryogenic temperatures. The propo...

A Reconfigurable TDM Hardware Accelerator for adLIF Spiking Neural Networks

I paradigmi tradizionali di visione artificiale basati su frame presentano limitazioni significative nelle applicazioni di edge computing in tempo reale, a causa della ridondanza temporale e degli elevati requisiti di larghezza di banda. I Dynamic Vision Sensors (DVS) offrono una soluzione efficace. Emulando la retina biologica forniscono un'acquisizione dati asincrona e guidata dagli eventi (event-driven), garantendo una precisione al microsecondo e un'elevata gamma dinamica. Tuttavia, si ri...

Stacked-Cell Power Amplifier Design based on Technology Characterization and Modeling

The continuous evolution of wireless communication, radar, and sensing systems toward millimeter-wave (mm-wave) frequencies imposes increasingly stringent requirements on Radio Frequency (RF) power amplifiers in terms of output power, efficiency, linearity, and reliability. Gallium Arsenide (GaAs) pseudomorphic high-electron-mobility transistor (pHEMT) technologies continue to offer a compelling solution for these applications due to their superior high-frequency performance, linearity, and p...
