On-Die Power Rail Measurements: Setup and Best Practices
Accurate on-die power rail measurements depend on proper sense-line design, differential probing, and careful test setup at the package level.
Educational materials about measurements of clock and serial data jitter using oscilloscopes. Understand the full range of jitter measurements along with time, statistical, frequency and phase-noise views of jitter with jitter deconvolution and extrapolation for advanced high-speed serial data applications.
By correlating filtered power rail variations with clock period tracking, you can quantify and verify a clock’s jitter sensitivity to supply noise.
By injecting a controlled power rail perturbation and tracking clock period variation, you can quantify a clock’s sensitivity to supply noise.
