Note that to run the Excel files posted here, you have to have macros enabled.  Files have been tested on Windows only: 32-bit xls files on Windows7 with 32-bit Excel; 32-64-bit xlsm files on Windows7 with 32-bit Excel and Windows10 with 32-bit and 64-bit Excel.  32-bit xls files are posted for sake of backward compatibility and because they run some of the macros much faster.

PDN filter illustration file: 32-bit xls, 32-64-bit xlsm.
Causal bypass capacitor model
True waveform of the output ripple of buck converters: 32-bit xls, 32-64-bit-xlsm. 

 
Causal bypass capacitor model
Causal frequency dependent impedance of a bypass capacitor based on integral Debye dielectric loss and causal conductive loss model parameters: 32-bit xls, 32-64-bit xlsm.

 
Dk-Df
Right-click here and save the Microsoft Excel demo illustration file. It calculates the causal frequency dependent dielectric constant and loss tangent dielectric model parameters.

lossy-trace
Right-click here and save the Microsoft Excel demo illustration file. It calculates the causal frequency dependent characteristic impedance, group delay, per-unit-length capacitance, inductance, resistance and conductance parameters of a homogeneous uniform interconnect.


Right-click here and save the Microsoft Excel demo illustration file. It calculates the time-domain harmonic composition and harmonic magnitude series of user-defined waveforms with selectable rise and fall times. 


Right-click here and save the Microsoft Excel demo illustration file. It calculates the skin-depth, shield impedance, reflection, absorption and total shielding.  


Right-click here and save the Microsoft Excel demo illustration file. It calculates the frequency-domain responses of a single capacitor and four parallel bypass capacitors with user selectable C, ESR and ESL.  Note: you have to enable macros to run the sweep function in the file.


Right-click here and save the SPICE input file to calculate the DC solution on a 20x20 resistive grid.  Note that you need SPICE (e.g., the free Berkeley SPICE) to run the simulation.




Right-click here and save the Microsoft Excel demo illustration file. It calculates the self impedance of bare rectangular parallel plates at arbitrary locations, with open or shorted boundaries.  Note: you have to enable macros to run the calculations.


Right_click here and save the  Microsoft Excel demo illustration file. It plots the self and transfer impedance surface of planes with a capacitor.  Note: you have to enable macros to run the sweep function.


Right_click here and save the  Microsoft Excel demo illustration file. It plots the impedance-measurement errors with VNA S11 and S21 data. Note: you have to enable macros to run the sweep functions.
