Semiconductor laser diodes (SLDs) are often packaged with a photodiode. The output current from this photodiode can be monitored to regulate the output power intensity of the laser diode. SLDs, however, are prone to pathological drifts, such as temperature variations and mode-hopping, that can alter the output intensity. A popular approach to stabilize the output intensity is to first convert the photodiode current to voltage.

Inductor-inductor-capacitor (LLC) resonant converters have a couple of appealing characteristics for applications requiring an isolated DC/DC converter such as minimal switching losses, no reverse recovery when operating below the resonant frequency and the ability to tolerate large leakage inductance within the transformer. The challengeA primary challenge when designing an LLC converter with a wide operating range is the behavior of the gain curve with respect to equivalent load resistance.

In April 2012, EDN published a circuit by John Fattaruso that lets you quickly measure the drain-source saturation current and the pinch-off voltage of both an N-JFET and a P-JFET. The pinch-off voltage (Vp) is measured by inserting a very large resistance between the source and the ground. The drain-source saturation current (IDSS) is measured by inserting a small resistance between the source and the ground.

For those who may not know, Mike Engelhardt is the author ofLTspice, which was originally produced by Linear Technology and eventually bought by Analog Devices Inc. LTspice was not Engelhardt’s first rodeo with writing simulators; he got his start in the 1970s simulating particle collisions at a physical lab and later writing a simulator for a scanning electron microscope, a program that ran on a cluster of Sun workstations at the time.

Machine intelligence enables a new era of productivity and is becoming an integral part of our lives and societies across many disciplines and functions. Machine intelligence relies on computing platforms that execute code, decipher data, and learn from trillions of data points in fractions of a second. The computing hardware for machine intelligence needs to be fast, extremely reliable, and powerful.

At the end of last year, the global software-defined vehicle (SDV) market size was valued at $49.3 billion. With a compound annual growth rate exceeding 25%, the industry is set to skyrocket over the next decade. But this anticipated growth hinges on automakers addressing fundamental architectural and organizational barriers. To me, 2025 will be a pivotal year for SDVs, provided the industry focuses on overcoming these challenges rather than chasing incremental enhancements.

Editor’s note:In this DI, high school student Tommy Liu modifies a popular low-cost DIY oscilloscope to enhance its input noise rejection and ADC noise with anti-aliasing filtering and IIR filtering. Part 1 introduces the oscilloscope design and simulation. This part (Part 2) shows the experimental results of this oscilloscope.

作者 : Aalyia Shaukat 物聯網裝置資安標準加速演進，業界正積極建構裝置安全防線，從晶片到系統導入多層保護機制與驗證標準，打造可信任的智慧連網環境… 物聯網(IoT)裝置的新安全標準正持續發佈，顯示安全性在嵌入式產品設計中已不再是事後才考慮的因素。今年初，美國白宮推出了「網路安全信任標誌」(Cyber Trust Mark)的安全認證產品標章，這是針對物聯網裝置安全性的一大舉措，提出了「動態安全標籤」(living label)的概念，更完整反映資安在產品生命週期中具有動態變化的特性。 該標準基本要求具備該標章的裝置需印有一個可供掃描的QR Code，用戶可藉此獲取安全資訊，例如裝置是否具備自動軟體更新功能(如資安修補程式等)。根據美國聯邦通訊委員會(FCC)的說明，IoT產品廠商需與經認證且獲FCC認可的“CyberLAB”合作，以確保其產品符合該資安計畫的要求。 《EDN》編輯不久前採訪了芯科科技(Silicon Labs)資安長Sharon Hagi，在此次對談中進一步探索此項新標準的背景、演進，以及此QR Code標籤制度未來的更多應用可能性。...

Electronics are everywhere. As daily life becomes more digital and more devices become software defined and interconnected, the prevalence of electronics will inevitably rise. Semiconductors are what makes this all possible. So, it is no surprise that the entire semiconductor industry is on a path to being a $1 trillion market by 2030. While accelerating demand will help semiconductors reach impressive gains, many chip makers may be held back by the costs of semiconductor design and manufacturing.

Wide-bandgap (WBG) semiconductors, namely silicon carbide and gallium nitride, have been an emerging frontier in power electronics, rapidly replacing conventional, silicon-based power devices such as IGBTs and superjunction MOSFETs in applications throughout the power spectrum. However, to fully maximize the benefits of WBG tech, system redesign is essential. It is not possible to follow the normal, relatively sequential path that is often taken for conventional, silicon power circuit design.
