  • How do I measure power distribution network (PDN) impedance?
    The 2-port shunt-through impedance testing method is the gold standard for measuring a power supply's output impedance and a PDN. It can also be used to measure the loop gain (phase) and assess stability performance.
  • What is ground bounce?
    What is commonly referred to as supply and ground bounce is really the inductively coupled cross talk between I/O loop inductances. This inductively coupled cross talk is created when the wide data bus of an IC shares a common supply and return lead, which has parasitic inductance. Simultaneous switching noise (SSN) is often also referred to as Vcc bounce or ground bounce.
