Operational amplifiers (op amps) may initially look intimidating, but with a bit of study, they can be easily understood and used in a variety of applications. Op amps can be thought of as a perfect ...

The purpose of this lab is to learn how to use operational amplifiers (Op Amps) to construct basic amplifier and signal conditioning circuits and to discover the performance limitations of the devices ...

A persistent issue with Op-Amps is thermal drift — a phenomenon where the amplifier’s input offset voltage varies over time and with temperature fluctuation. Operational Amplifiers (Op-Amps) are ...

An Arduino Shield to measure an FSR using either a buffered voltage divider or current to voltage op-amp solution. We needed is an instrument that can plot the voltage/thrust curve for any motor and ...

The simulator is distributed free of charge and is under continuous development. QSPICE software is an analog and mixed-signal simulator characterized by high simulation speed, accuracy and ...

Operational amplifiers (op amps) and comparators have two inputs, inverting and noninverting, and an output that can usually swing from rail to rail and have the same schematic symbol. So, what’s the ...

We have built an atomic force microscope using a quartz tuning fork as sensor. The excitation method we adopted, the electrical excitation, introduces stray capacitance into the signal-processing ...

As part of our Op-Amp Challenge we’re seeing a wide diversity of entries showcasing the seemingly endless capabilities of these extremely versatile parts. Another one comes from [Joseph Thomas], who ...
