My Electronics calculators:

I make sometimes excell based electronics calculators, to make my work easyer.You can download them here.

In the webpage http://circuitcalculator.com/wordpress you can find more calculators, from other people.

Mostly the file links work only with Internet Explorer !

(In reverse chronological order)

With this tool, you can determine PCB design rules or you can check if the already designed system

meets the timing requirements, or not. Timing analysis is very recommended for high-speed digital systems.

An earlier version is available here.

This is a calculation-sheet file to be used in the free program the Smath Studio, to calculate power dissipation

in the indusctor and the power switches in a DC/DC converter. The program is available here.

If you want to get an accurate frequency-dependent characteristic impedance of a transmission line,

Then you can use a general purpose 2D field solver, like the FEMM to simulate for RLGC parameters.

If you have them, you still need to get the impedance, so you can put them together here.

This calculator also calculates frequency dependent dielectric constant, and the G parameter from the others.

Most of the PCB trace impedance calculators dont take the signal frequency into account.

With this calculator, you can fill this gap, by providing frequency-pre-compensated dielectric constant to them.

These are QUCS simulator schematics template files. It can help you in doing macromodeling, simulation

and design of system-level power distribution networks for CPU/FPGA core and IO power rails.

With this calculator, you can make an estimation an the PCB interconnect loss budget for your high-speed

serial interconnections, like PCI-express, or SATA.

With this, you can match trace lengths whose are on different layers. However, its recommended to put all

Your signals what you have to match, ont same structure layers.

With this tool, you can calculate trace lengths, adjustments for memory-interface PCB-design

With this tool, you can try how your controlled impedance traces will look like on a selected PCB stackup.

If you work with high speed PCB design, with this tool you can calculate or compensate the effect of the

Permittivity variation over frequency.

With this tool, you can make a timing analysis for an SDRAM memory and embedded processor based system.
