Capacitor Impedance Evaluation from S-Parameter Measurements

This article explores S21 parameter methods for measuring capacitor impedance. Comparing two-port shunt and series techniques with established benchmarks reveals the two-port shunt method delivers superior accuracy across multiple capacitor values and frequency ranges.

Understanding ESD Control: ESD Prevention

By understanding resistance in discharge circuits, engineers can implement effective protection through grounding, dissipative materials, and equipotential bonding—creating comprehensive ESD control programs that safeguard sensitive electronic components.

Bonding to the Ground Plane

Discover how different standards require various approaches to bonding equipment under test to ground planes. Learn the critical differences between MIL-STD-461, CISPR 25, and ANSI C63.4 that could impact your compliance testing results and save you costly retesting.

Noise Suppression Techniques Using Capacitors

Explore the essential role of capacitors in electromagnetic interference (EMI) suppression. From ceramic to electrolytic options, discover how proper selection and placement of these components can significantly improve circuit performance and reliability in electronic design.

Soft Disciplines

Engineers often undervalue communication skills during their education, focusing solely on technical courses. This article argues for changing the public perception of engineers from "techno-nerds" to articulate professionals by encouraging them to engage with their communities and share their work.
