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 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.

Autonomous drones and robots utilize small motors. These fast-spinning mini motors require miniature encoders and IC package sizes. This article shows how an optical sinusoidal encoder provides a higher resolution and increased speeds with a 2x3 mm dual simultaneous-sampling SAR-ADC.

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.
