In this video we will discuss circuits that use an operational amplifier to compare the amplitude of one signal to the amplitude of another signal or to a reference voltage. These analog comparator circuits can produce output signals that are compatible with digital components.

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. Even signals that would be completely blocked by a typical silicon diode, because they never exceed the diode’s threshold voltage, can be precisely rectified by an active rectifier.

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.

The operational amplifier is a versatile, user-friendly component that has been incorporated into an endless variety of circuits and applications. One reason for the op-amp’s popularity is its ability to combine simplicity and performance: op-amp circuits are a valuable addition to many types of systems, yet they are not difficult to design and often require very few external components. In this video we’ll be exploring the voltage follower, which is a good example of an op-amp circuit that is simple yet very useful.

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.
