ADE calculator rms voltage and power

[praveen450]

Hi,

In cadence analog design environment, I'm using caluclator to check rms voltage of a circuit.

Does it give vpeak/squarroot(2) instead of Vpeak-peak/squareroot(2)?.

If I plot the power wave and take the rms value of it, should I multiply the rms power four times?.

Thanks in advance

rms() function gives Vpeak/CF, where CF means "Crest Factor".
If signals are pure one-tone sinusoidal, CF is sqrt(2).
See https://en.wikipedia.org/wiki/Crest_factor

Note : rms() is for results of transient analysis.
If your signals are results of ac analysis, you can't use rms(). In this case, use Vout/sqrt(2) simply without invoking rms(Vout).
