This article showcases the advantages of an op amp loop-stability analysis method that I use myself and recommend to others. This method looks at the behavior and rate of closure of the open-loop gain ...

After my last Signal Chain Basics article, The basics of op amp loop-stability analysis: A tale of twin loop-gains, I received questions about how to generate the open-loop SPICE simulation curves ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

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 ...

b. The gain is set by VCC as the higher the supply voltage, the higher the gain. c. By the value of R3 as this resistor to ground sets the offset bias seen by the op-amp hence the gain. d. By the ...

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 ...

My hands-on introduction to operational amplifiers was in 1969 while in the army as a junior scientist in the Atmospheric Science Laboratory at the White Sands Proving Grounds. We had taken a ...

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 ...

Introduction to fundamental concepts and applications of electrical engineering. Topics include: circuit analysis from dc resistive networks to networks of impedances operating in the sinusoidal ...
