Abstract: Barometric pressure sensor are indispensable features in wearable consumer devices. Modern designs can sense absolute height difference of less than 8.5cm (1Pa), improving indoor navigation significantly and enabling new applications such as activity tracking and crash detection. In this talk, we will take a deep dive into the design challenges of readout chains for […]

Abstract: The first vacuum tube amplifiers appeared circa 1912 and were used originally as audio amplifiers. Shortly thereafter they helped to popularize AM radio broadcasting. Generating sufficient broadcast power was difficult and electricity costs were high for operators, driving many key innovations to improve output power and efficiency, particularly when amplifying signals with large peak-to-average power […]
