PMIC – OR Controllers and Ideal Diodes: Intelligent Power Path Management for High-Reliability Systems

We position PMIC – OR Controllers and Ideal Diodes as a cornerstone technology in modern power management architectures, designed to ensure seamless power source selection, redundancy, and protection with minimal power loss. These devices replace conventional diode OR-ing solutions by delivering near-zero forward voltage drop , fast switchover , and intelligent fault isolation , which are essential in high-availability and energy-efficient electronic systems. OR controllers and ideal diodes are widely deployed in telecommunications infrastructure, data centers, industrial automation, automotive electronics, medical equipment, and battery-powered systems , where uninterrupted power delivery and efficiency are non-negotiable. Fundamental Concept of Power OR-ing Traditional Diode OR-ing Limitations Conventional diode OR-ing uses Schottky or PN diodes to connect multiple power sources to a common load. While simple, this approach introduces significant drawbacks: High forward vol...

RF Detectors: Principles, Architectures, and High-Performance Applications

We present RF Detectors as essential components in radio frequency systems, enabling the conversion of RF signals into usable baseband information such as voltage, current, or digital data. RF detectors form the analytical core of countless electronic platforms, providing accurate signal presence, amplitude, power level, modulation envelope, or frequency-related information. Their role spans wireless communications, test and measurement, radar, industrial sensing, consumer electronics, and defense systems . By translating high-frequency signals into measurable parameters, RF detectors enable control, monitoring, protection, and demodulation functions that are fundamental to modern RF and microwave design. Fundamental Operating Principles of RF Detectors RF-to-Baseband Conversion At the core of every RF detector lies the process of rectification and filtering , where alternating RF waveforms are converted into a proportional DC or low-frequency signal. This baseband output repres...
