Voltage regulator impedance characterization is a straightforward concept but the challenges in making highfidelity measurements are numerous as the impedance becomes progressively smaller. This paper evaluates techniques used for low impedance buck converters requiring large-signal current perturbations to properly characterize the impedance. Additionally, the paper addresses how high-performance time-domain characterization equipment can be utilized to generate frequency-domain impedance
