壓電發聲器驅動器如何在更寬廣的電池電壓範圍內提高聲壓級
壓電發聲器在許多產品應用中，用來產生警告或警示音，通常用於可攜式、電池供電和節省空間的產品。這些裝置由連接到金屬板上的陶瓷元件組成，對裝置施加電壓時，陶瓷元件產生的壓電效應，會讓金屬板變形。隨著電壓的變化，陶瓷元件會跟著收縮和膨脹，連接的金屬板也因此振動而發出聲響。

New Advances in LED Control Systems for Automotive Exterior Lighting
The automotive lighting market continues to grow strongly and is forecast by analyst Yolé to reach US$38.8 billion by 2024. Over the past few years, LEDs have taken an increasing share of this market, and LED exterior lights have become a familiar sight on our roads.
PCIe Generations from Leading-Edge to Legacy, Desktop to Data Center
The global appetite for data shows no sign of abating and continues to place pressure on service providers to handle more bits, more quickly.
Brushed DC Motors and How to Drive Them
DC electric motors have been around for nearly two hundred years, with a steady series of refinements in that time. More recently, brushless DC motors have become increasingly popular but for many applications brushed DC motors are still the right choice.
晶體振盪器如何讓數位電子裝置同步化
在家裡或工作中遇到的大多數電子系統將包括至少一個振盪器作為時鐘工作，提供準確的定時，同步操作或作為頻率參考。在這裡，我們將看到使用石英晶體振盪器的許多好處，並討論可用的選擇。
BoM and PCB Space Savings Achieved with Control Channel Aggregation for Optical Interfaces
Fibre optic networks bring the promise of fast broadband to new customers all around the world. It increasingly reaches new limits, but to provide a guaranteed level of service, that bandwidth must be managed effectively. A significant factor to that effectiveness is how it interfaces with other network equipment running over copper cable.
Integrated Solutions to USB Type-C Port Implementation Challenges
Highly integrated solutions for USB 3.2 data switching, USB Power Delivery and USB Battery Charging control, and transient protection help designers unleash the full potential of the USB Type-C interface.
汽車應用中新增瞬態電壓抑制功能
In automotive applications, it’s essential to protect sensitive semiconductor components against power surges, transients and electrostatic discharge (ESD). A single transient voltage spike could easily damage or disrupt a component, while electrical noise of even relatively low energy can cause significant interruption to digital communications.
Improving Power Conversion Efficiency with Super Barrier Rectifiers
For the design of almost any electronics or electrical system, it’s important to maximise power efficiency. In mobile devices, better power efficiency delivers longer battery life, which is a key selling point. For basically any application, improving power efficiency means that size and weight can be reduced, and thermal management simplified – thus reducing costs. Of course, using less power also helps products to meet energy rating requirements, which may be a legal requirement, and an attractive feature for customers.
自然語言就是新一代的使用者介面
The ‘perfect storm’ of high bandwidth internet connectivity, deep learning algorithms and high-quality audio is enabling a new paradigm in user interfaces: the spoken word. The ability to interact with household appliances and cloud-based services through natural language is truly a sea-change in the way people and machines interact.
