In the high-speed digital world, the voltage regulator module (VRM) is often neglected in the simulations or a simplistic resistor-inductor model is used to represent this VRM. While the resistor-inductor model is better than nothing, it misses most of the VRM noise. A switching VRM produces noise in many ways, including switching related ripple and spike noise. There is also noise due to switching frequency jitter. Other noise sources include input voltage related transients and turn-on overshoot. By following just a few simple rules, a fast, highly accurate model can be created from a simple measurement or two. Once the model is available, the design can be easily optimized and confidently applied in your project.
