Impedance Calculator
Circuit Design Suite Software Utility
CAD Design Software offers the Impedance Calculator, a software utility tool allowing you to make fast impedance calculations on the fly. With the new version 1.2, the calculator offers expanded materials, further improving your design needs. The CDS Impedance Calculator is the only software utility that will quickly fine tune trace and substrate structures with geometry calculations based on input target impedances and has the capability to allow for trace etch taper and a separate dielectric constant for solder mask.
The CDS Impedance Calculator performs two-way calculations for various differential Microstrip and Stripline configurations between the following parameters:
- Line width
- Differential line width & spacing
- Substrate thickness
- Impedance, and dielectric constant
Impedance Calculator is included in the following Circuit Design Suites:
