Problem in calculation of Power dissipation

raghavendra ks

 i have the schematic of a double tail comparator where i need to calculate the power dissipation factor. I am simulating the circuit using Spectre simulator. could anyone tell me what is the procedure for calculation of power...

    I'm not sure what  you mean by "power dissipation factor". I know what "dissipation factor" is (it's the inverse of Q, i.e Quality Factor), and I know what "power dissipation" is (presumably the power consumed by the circuit).

    If it's the latter, then wouldn't you just measure the current through the supply source and then plot V*I (where V is your supply voltage) and probably compute the rms() of this using the calculator?

    Regards,

    Andrew.
