High Performance Class-D Amplifiers

Shoubhik Karmakar

This dissertation presents advancements in Class-D audio amplifier design, addressing the key challenges of system cost and size, electromagnetic interference (EMI), and audio fidelity in modern applications. The research develops two innovative amplifier prototypes targeting automotive and piezoelectric speaker systems. The first prototype introduces a hybrid ΔΣM-PWM modulation scheme to meet stringent automotive EMI standards while maintaining high efficiency and audio quality. The second prototype eliminates the need for external damping resistors in piezoelectric speaker drivers, significantly reducing system cost and size. Measurement results validate the performance of the proposed designs, demonstrating state-of-the-art efficiency, EMI suppression, and audio fidelity. This work contributes to the development of cost-effective, high-performance audio amplification solutions for diverse consumer and automotive applications.

Silicon Retina Event Camera Design

Event cameras are vision sensors that mimic biology’s activity-driven digital output. They offer a unique combination of low latency, high dynamic range, and sparse output that makes them attractive candidates for embedded vision systems that face the power-latency tradeoff of conventional frame cameras
