Hello,

I want to measure the power consumption of charge pump (its a double dickson charge pump built using switch cap circuits). Can anyone suggest how to measure the power in any state?

When I try to measure the current going through the supply, there are spikes that settle down within the clk period. Do I have to integrate this current?

I am using cadence virtuoso tool, please suggest how to measure the power using this CAD tool.

Thanks in advance!
 

In your analog environment go to outputs/setup, name power somehow, open calculator tool, make an expression and use it. In calculator you can built almost everything you need, I think in your case you need average(Vdd*Idd). You want to measure power consumption of your control? For input/out power it will be similar, however for individual losses it will be a bit tricky.
