How to Design a Stable High Frequency Amplifier

Stable High Frequency Amplifier

This short video series introduces stability analysis in high frequency circuit design. Stability analysis is becoming much more critical in modern high frequency applications because gain and coupling cause new problems to arise that are not easy to resolve in the lab. The first video is an introduction, presenting an example where a popular stability design technique called K-factor (or…
