Lesson 1 - The Trouble with K-Factor and the Paradox of Choice


In this course, you'll learn about stability analysis in high frequency circuit design. Stability analysis has become even more critical to modern high frequency applications in recent years because gain and  coupling cause new problems to arise that are not easy to resolve in the lab. Expert RF designer, Matt Ozalas will guide you through the high frequency amplifier design process, covering everything from basic concepts such as K-factor to more complex real-world design examples.
