智能电源管理系统中的机器学习

Machine learning for MCU implementation (tiny ML) is a growing field that offers new and enhanced functionality for battery management and motor control. ML algorithms discover information and patterns in complex sensor data that can be used to optimize performance and improve understanding of overall system health. In addition to advances in tiny ML techniques, the availability of AutoML tools that automate the collection of data, training of ML algorithms, and generation and deployment of MCU firmware is on the rise. Such tools, combined with access to system on chip (SoC) sensor data, enable the development of ML-based solutions in today’s power management systems. This paper discusses the development of machine learning (ML) applications using Qorvo’s intelligent power management systems ICs. Qorvo's highly integrated power management SoCs combine Arm® Cortex® M0 and M4F MCUs with an analog front end with an array of sensors to enable smart control and monitoring functions.

应对现代应用中最常见 RF 滤波挑战的四种方法

RF 滤波器已经存在很长时间了。就是因为时间长，以至于人们可能会认为理所当然是必要的。如今，最新的 5G 和无线应用受到了很大的关注，这些应用正在推高数据速率和数据容量。但是，对速度更快、性能更强产品的需求也意味着新的挑战，因为这些趋势增加了信号干扰的概率。因此，RF 滤波器技术成为了一个关键的设计因素。体声波 (BAW) 和表面声波 (SAW) 技术正在不断发展，以应对这些挑战。
