Impedance matching simulations using PSPICE

Impedance matching is a critical skill required for a large number of electronic circuit designs. A number of popular techniques are used over and over again and many are inbuilt into certain software packages. However, if one wishes to check out the matching using an independent package like PSPICE it becomes interesting to see what impedance matching means in the PSPICE domain. This allows the designer to check and re-check his design with a simple tool that is freely available in the industry, both as freeware and as a purchasable package with many “bells and whistles”. Ultimately though it is engineering judgement that counts and a simple way to check one’s work is always desirable. Please visit the Signal Processing Group Inc., website and check under the ” free articles…” menu item for an article addressing the impedance matching simulation technique and its interpretation.

We design and deliver analog and RF/wireless ASICs and modules using state of the art semiconductor, PCB and assembly technologies. Please contact us at for a quote and a proposal.
