Advanced function with Virtuoso Cadence

zizo2012

Hello,
I work on the characterization of an amplifier circuit in Cadence Virtuoso and I do not know how to perform some function in the calculator.Please can you help me and send me an advanced tutorial on the use of this software or help me by answering the following questions and I will be very grateful?
Q1: How to determine the parasitic impedance (R, C, L) of a circuit in Virtuoso and trace the signal of the real part and the imaginary part (in dB) versus frequency?
Q2: How to determine the value of the harmonic distortion of the output signal, and how to plot it versus the frequency?
Q3: How to identify and trace the change in equivalent noise brought back into function of frequency?
Q4: How to determine the power dissipated by the circuit?
Thank you.

  • Dear zizo212,

    Is there a reason you cannot use a current probe in series with an ideal supply (or supplies) connected to the power node(s) of your circuit block? After the simulation completes, taking the average of the current through the probe and multiplying it by the respective supply voltage will provide the average power. The instantaneous power may also be determined. Perhaps I am misunderstanding your question - my apologies if I am!
