[SOLVED] Node Floating in Pspice simulation

[panda1234]

Hi guys,
this is my circuit.
Error says Node between two capacitor is floating.

Yes, it is.

That's a problem at least in transient and bias point analysis. You need to add a high ohmic resistor (e.g. Gohm range) parallel to one of the two capacitors.

Keep in mind that each node needs a dc path to ground (or to a voltage source). This path can be a resostor as high as 1E12 ohms.

Thanks,I have another question:in spice simulation how i realize what's the direction of current?

Re: Current direction in simulation

Generally currents "flowing" into a device are counted as positive ("added, +"), currents out of a device are negative ("subtracted, -").
