In this video we will discuss the active rectifier, which is an op-amp-based circuit that uses a normal diode in conjunction with negative feedback to rectify signals without generating a significant amplitude difference between the input voltage and the rectified output voltage.

In this video we’ll study an op-amp-based current-to-voltage converter. This widely used circuit is a simple and effective means of converting the output of a current source into a typical voltage signal.

In this video, we’ll look at some circuits that represent common op-amp applications. We’ll start with the voltage follower, then we’ll move on to an inverting amplifier, an active filter, and a current-to-voltage converter.

In this video we will examine the internal circuitry of an operational amplifier. A thorough analysis of any professional-quality op-amp would be far too complicated for an introductory video tutorial, but if we focus on the overall architecture and a few specific design techniques, we can learn quite a bit about op-amp functionality without getting lost in the details.
