urgent help: cadence simulation!

[foxbei]

I'm designing a switch cap ckt now and I want to get a graph of "voltage vs. temperature" for my ckt simulation. does anyone know how to get this kind of graph? thanks. I'm really in urgent.

you can do it by dc analysis.

In analog environment, choose analysis tap.
then choose dc tap & check temperature box.

thanks. but for a sw cap ckt, you can't run dc analysis because for dc, the sw cap is open ckt. the only thing u can run is transient analysis. from that, u can see the ckt is switched back and forth. and in order to get different temp, you can run temp parametic. but my question is: how can i draw a pic of output voltage vs. temp? thanks again.

Oh, foxbei, I misunderstood,
In that case, How about giving initial state?
In sc circuit, the circuit is switched back and forth, as you said.
And in the case of SC-amp, there are amplification phase & other phase.
If you give initial state to the circuit for closed loop configuration, you can get DC analysis, I think.

Regards.
