Title: How to find average power only during the POSITIVE HALF CYCLE for a given time?
Post by Bean Nakamura on Dec 5^th, 2016, 8:04pm

Hello all! :)
I tried to post this question on the Cadence forum since last month but there seems to be a problem posting on it.
Is there any way I could find the average power of the attached rectifier circuit but only during the positive half cycle using Cadence Virtuoso GUI? I am designing a rectifier to work at 915MHz. I am well aware that I need to integrate v(t)*i(t) over a specified time.
So if I wanted to integrate only the positive cycle, the intervals in which I'd integrate over would be from 0 to (1/2*915MHz). Problem solved right? Not quite, since this would only take into account the first period. What if I wanted to do this for 300us? I can't just find how many periods are in 300us and times the power in the first period by that because the values of the first period and other periods are different. I don't know if this makes sense or not but I really hope it does lol. Any non-scripting methods of doing this using Cadence Calculator/ GUI?I am not familiar at all with scripting and netlisting so any GUI-based help would be greatly appreciated!

Thanks!

Bean,

You can create a dummy signal, a voltage pulse of 1V/0V. Multiply
the output by the dummy to eliminate the negative half of the signal.
Then integrate the waveform.

Great idea Sheldon! Will try doing that right away. Thanks for the suggestion! :) :)
