Digital Power Supply Loop Design Step-by-Step: Part 2


In the previous article, we showed that the output of almost any op-amp compensator can be emulated in the digital domain with a single linear difference equation. We then created a simple op-amp integrator/compensator, presented its linear difference equation (LDE) in the digital domain and then plotted the output of the op-amp commentator vs its digital equivalent LDE. We saw that the output of our mathematical equation in the digital domain was almost exactly the same as the op-amp circuit in the analog world.
