VNA Impedance Measurement for Power Distribution Networks
Indianapolis, January 15, 2019 -
Copper Mountain Technologies'
Steve Sandler will present a webinar on January 22, at 11 am EST, about
VNA Impedance Measurement for Power Distribution Networks. Almost
all modern circuits are sensitive to power quality, which to a large extent is a measurement
of the power rail impedance. This is because flat impedance power rails result in much
lower noise than power rails that aren't flat. In RF circuits the peaks generally result
in increased phase noise, while in digital circuits the issues are related to the allowed
voltage window for the ASICs. In high-speed transceivers, these peaks result in jitter,
which is also related to phase noise. In analog circuits, the peaks can result in increased
noise density and in analog to digital converters the peaks result in spurious responses.
The power rail impedance is typically controlled by the careful selection of bulk aluminum
or tantalum capacitors, ceramic decoupling capacitors, inductors, and ferrite beads.
The instrument of choice for these impedance measurements is a vector network analyzer
and the most common and highest accuracy measurement is the 2-port shunt through technique,
using a 2-port VNA. The VNA offers the excellent dynamic range and also wide bandwidth.
