Finding DC operating points at certain timepoints during TRANSIENT analysis

RFStuff

Dear All,

I need to run transient analysis of a circuit.

However, I also want to find the dc operating points of some components at certain instants ( time points) during  the transient analysis on the FLY. The operating points may be logged to a file for analysing the data after the transient simulatuion is OVER.

Could anybody please tell, is there any way of achieving this. I use IC5141 & MMSIM12

Kind Regards,

Parents

  • Hi Andrew,

    Maybe this is hashing up the old stuff, but like the previous question, I would like to calculate the DCOP at certain transien time. Basically, all the capacitors should be removed and the inductors are open at the specified time.

    I tried this on a very simple RC circuit, in which the resistor and the capacitor are parallel. I placed an initial condition on top of the resistor and capacitor. I performed a transient analysis first. Let's say I see at 50uS simulation some voltage level on top of the RC, let's assume 100mV.

    Once I do infotime at 50uS and back annote the results then I should see 0V, right? Because, the cap should be discharged completely? Is my expactation from the infotime correct?
