  • Abstract
    An FPGA-based class-D power amplifier is designed for driving an ultrasonic transducer. The amplifier is capable of automatically detecting and tracking the transducer´s resonant frequency, driving the transducer right at its resonance for maximizing vibration efficiency. The design focuses on devising resonant frequency tracking and optimal modulation algorithms that are suitable for FPGA implementation.
