Collaboration to develop broadband silicon capacitor simulation model

Modelithics has developed two equivalent circuit model versions, one that features validation to 67GHz, based on testing done in microstrip format offering substrate and pad scalability, and another that is validated to 110GHz, using test data obtained with a coplanar waveguide fixture on quartz thin film. This 10nF silicon capacitor in a 100μm 0201 form factor shows the following performances:

• Flat frequency response (insertion loss < 0.4dB up to 67GHz & < 1.2dB up to 110GHz)
• Excellent return loss better than -20dB
• Resonance free thanks to the capacitor single layer design of 50μm thickness
• Zero piezoelectric effect and low dielectric absorption (0.05%) at least 12 times lower than ceramic capacitors
• Ultra low electrical variation over voltage and temperature (lower than 1%).

IPDiA is sponsoring FREE 90-day licenses for use of all Modelithics models available for IPDiA capacitors, which are also now included in Modelithics COMPLETE Library. This includes the two new equivalent circuit model versions for the 0201M (10nF, 100μm thickness, 11V breakdown voltage), plus Modelithics S-Parameter data models for other values and variations of the ultra broadband silicon capacitor series.

The IPDIA model sub-library is now available for easy installation and use in five popular microwave simulation tools: Keysight ADS, Keysight Genesys, NI AWR Design Environment, ANSYS HFSS and Sonnet Suites.
