Operational amplifiers (commonly called op amps) are a ubiquitous building block for designing electronic circuits. Today, these devices are fabricated as small integrated circuits, but the concept ...

Maybe you are familiar with the op-amp as an extremely versatile component, and you know how to quickly construct a huge variety of circuits with one. Maybe you even have a favorite op-amp or two for ...

Previously I discussed how to use a spreadsheet to visualize an op amp's Noise to help pick the lowest noise for any source resistance [1]. In this article we will use Texas Instruments capable SPICE ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

Native SPICE elements that accurately replicate an op amp’s real-world behavior were nonexistent. A transconductance sourcing current from the rails and transitioning to a resistive state as the ...

Modeling the performance of an analog device with SPICE is one of the standard techniques used by circuit designers to perform initial characterization and performance analysis before putting together ...
