How do you calculate the power consumption of my board?

Hello

I need to estimate the power consumption of my PCB, I used some capacior, Inductor and diodes

pls help me out

You need to be more specific, it could be from almost zero to infinitely high depending on how you have them connected. Can you post a schematic?

Brian.

Thanks
There is the schematic

could you put a muttimeter in the power line to measure mAmps?

I didnt have muttimeter :/, There are any formula I calculate it??

Yes of course there is but the formula would be very complicated.

I would suggest the simplest method (which ignores phase shifts and residual capacitances/inductances but will give a reasonably accurate result) is to convert it to a resistor model and treat the antenna voltage, assuming that is the input, as DC. In reality it will be very frequency dependent.

So do this:

1. convert all the capacitors to equivalent resistances using the formula:
1/(2 * pi * f * C)

2. convert all the inductances to equivalent resistances using the formula:
2 * pi * f * L

3. for the diodes, subtract Vf from the voltage across them and calculate the power loss as Vf * I

Use the resistor as it is. The power loss in it is (V * V)/R

In the calculation, f is the frequency in Hz, C is in Farads, L is in Henries and R is in Ohms. When you have converted everything to it's equivalent resistance and calculated the total across the source, the power consumption is (source voltage * source voltage)/ total resistance.

As I said, the calculation is quite complex and will be inaccurate unless you also take into account the phase shifts and shape of the input waveform.

You can use a circuit simulation software. There are many spice-based software that are freeware.

Can you gives me any website that can help me!!!

If you are refertng to a website related to simulation software you can search LTSPICE, microcap, orcad; this last two have evaluation version which require registration
