The more recent Fully Differential Amplifiers (FDA) offer both CFA and VFA versionsThe CFA based versions will also have poor DC accuracy while more recent “precision” VFA based FDAs can provide much improved DC accuracy. Those VFA-based FDAs do come with some added DC error sources beyond the typical op amp terms that will be described here
This part 3 will progress through the different VFA approaches with Part 4 moving on to CFA and FDA DC precision considerations
Here, we will pick I/O range options for the remaining two most popular high-speed amplifier types: High Speed CFAs and FDAs
Some years back, an excellent blog appeared on EDN stepping through common issues and questions surrounding lower speed Voltage Feedback Amplifiers (VFA). A wider discussion of the unique issues that come with higher speed op amps will be the intent here
