    Link Description Op Amp Stability Basics: Part 1 VFB Op Amps: Overview of Bode plots. An intuitive model for an inductor, capacitor, and op amp. A simple, first order op amp stability check called…
  • Op-Amp Stability Basics: Part 1

    This video will introduce some basic tools and concepts for solving any op amp stability problem. Overview of Bode plots and their magnitude and phase relationships is presented. An intuitive model for…
  • Op-Amp Stability Basics: Part 2

    This video will focus on op amp output impedance, as a critical parameter for op amp stability, especially when driving capacitive loads. The output Impedance definitions of Zo and Zout will be derived…
  • Op-Amp Stability Basics: Part 3

    This video will show Zo and its interaction with a capacitive load that will create a Loaded Aol curve of two-poles. One compensation scheme for driving capacitive loads, Riso Compensation will be presented…
  • Op-Amp Stability Basics: Part 4

    This video will teach a Log Scale Trick and discuss how Aol can vary with process and temperature. In addition, for a dominant 2-pole system, the relationship between closed loop transient and closed loop…
  • Op-Amp Stability Basics: Part 5

    This video will cover the Dual Feedback Compensation technique and how to avoid the “Big Not” which can make an op amp even more unstable with this technique, if it is misapplied. A capacitive compensation…
  • Op-Amp Stability Basics: Part 6

    This video will cover Non-Loop op amp stability problems. These problems can be caused by an input bias cancellation resistor, PCB trace routings, power supply connections, the ground that is not always…
