Mechatronics 1: Week 4 - Operational Amplifiers

Operational Amplifiers: The Workhorse of Analog Electronics

Operational Amplifiers (Op-Amps) are versatile active circuit elements used in a wide range of applications from signal conditioning to active filters and control systems. This week, we will explore their ideal characteristics and fundamental circuit configurations that form the basis for many mechatronic systems. Select a topic below to learn more.

Interactive Sandbox: Non-Inverting Amplifier

Explore the behavior of a non-inverting op-amp configuration. Adjust the input voltage and resistor values to see how the output voltage and gain change. This circuit is commonly used to amplify sensor signals without loading the sensor.
