This article explains the expected behavior of on-die power rails during CMOS switching events, including PDN current flow, clock-edge noise, and asymmetric current draw between switching and latching operations.
Learn how oscilloscope histograms help characterize component specifications by comparing propagation delay, mean, standard deviation, and measurement spread under different conditions.
Foundational and advanced concepts for maintaining clean, reliable signals in high-speed designs. Covers measurement techniques, common pitfalls, and practical approaches to identifying and mitigating signal degradation in order to maintain signal integrity and power integrity in electrical designs.
A simple rise-time experiment reveals why every oscilloscope user must understand transmission line behavior when measuring signals with sub-10 ns edges.
Understanding how return currents flow—and why they follow the path of lowest loop impedance—is essential to controlling reflections, crosstalk, and EMI in high-speed designs.
Fast-rising signals can introduce transmission line reflections that appear as ringing on an oscilloscope, but proper 50-ohm termination can eliminate these artifacts.
What if we remove the probes from the equation by connecting our DUT's output directly to the oscilloscope's analog input using a 3-ft. 50-Ω coaxial cable?
