The popular FDA comes in both Current Feedback Amplifier (CFA) and Voltage Feedback Amplifier (VFA) variants. The CFA versions tend to be used in AC-coupled applications where their great full power ...

How Stable is your Op Amp or FDA design? One of the most important aspects of any end system design is to understand and improve (if necessary) the nominal phase margin for each stage. Since the early ...

Characterizing SSBW for VFAs and FDAs. What's hiding in some fully differential amplifiers? Measuring response shape and harmonic distortion. Adding an input common-mode control loop to a legacy FDA.

An electronic circuit that amplifies the difference between two voltages. With one regular input and one inverting input (+ becomes -, - becomes +), it multiplies the difference by a constant factor.

Who is involved with simulating op-amp design and developing their datasheets? Clarifications on sometimes obtuse amplifier specifications. Pitfalls to avoid when interpreting ac specs. What to watch ...

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 ...
