who can help me^^^
thanks^^^
 

For simulation , you can use .measure command in Hspice for calculating the power dissipation

thanks a lot. and do you know how to do hand calculate? ^^^
i only have a datasheet^^^
 

Usually the datasheet will have the information about power consumpation based on the some load and some frequnecy. and if you want to calculate other power consumption for different condition, you can use P=fcv^2.

f:eek:perating frequency
c:loading
v:eek:perating voltage.

Best regards,
Yibin.

you must consider the capacitance of PCB that is main power consumption.
