Average Current for switch capacitor resistance

[reactgary]

Hi,

I am simulating a switch capacitor resistor using Cadence schematic
capture and Spectre. How can I have got the average current through the
capacitor? I tried to use DC analysis but it fail to give me the
average current? What can I do ?

Here is the schematic I used in the simulation.

Do a transient, measure the current, and use the "average" special function in
the calculator.

Obviously the DC approach wouldn't work because circuit works by virtue of the
switches turning on and off periodically. It ain't going to give you much
average current if the switches are off all the time ;-)
