AMP II.6 – Amplifier Stability

So far, everything we’ve learned about negative feedback seems to indicate that it is a great tool with little drawbacks.  The only inconvenience we’ve actually talked about was a reduction in gain.  Choosing a device, or a cascade of devices, that provide a big enough gain to start with solves this problem.Unfortunately, negative feedback has…

AMP II.2 – General Feedback Theory

Introduction Before diving practical amplifier circuits, we need to address the underlying theory behind feedback amplifiers.  This chapter will contain the essential formulas and vocabulary to be able to move on to more practical topics. A Little Bit of Control Theory If you’ve studied automation, electronics, or mechanical engineering, chances are you’ve come across control … Read more
