Milli Ohm Measurements - Know how to Use Milli-ohm Meters Correctly

Image
  Processor power distribution network plays an important role in the proper working of a processor. A PDN is designed based on the impedance versus frequency characteristics. PDN design starts with the assessment of target impedance which is the ratio of maximum change is allowed voltage to the maximum change in current. The maximum change in current is usually taken as half the input current to a processor. To avoid ringing on the PDN, it is important to design the PDN as flat as possible. This reduces the radiated EMI issues. This also helps to improve the eye diagram for a transceiver chip. The most important issue in designing in the PDN is in measuring the PDN impedance.  Current industry standard chips are designed at the milli ohm impedance levels, and measuring impedance at these levels are a challenge.  High end processors are designed with micro ohm impedance levels. Another challenge is that they have to measured at the highest frequency of interest – usually ...

Know the Characteristics of the Power Supply Testing Kit

Image
Power supplies are an important part of any electronic system. Older designs used to use linear power supplies. However, linear power supplies have a lot of power loss. Modern designs use switching DC-DC converters for power supplies. The main advantage of the switching DC-DC converters is that they have very high efficiency compared to linear power supplies.    All power supplies have input impedance, output impedance, reverse transfer impedance, PSRR. Loop stability is another important parameter for a power supply. Test and measurement of these parameters are of utmost importance in power supply design. Input and output impedance of a power supply require DC biased impedance measurement. Measuring impedances in the range of ohms is easier with good accuracy. The real measurement challenge comes into play when we need to measure very low impedances, in the range of milli and micro ohms. Various factors need to be studied to perform high fidelity low impedance measurements. U...
