Steady-state analysis: PSpice Capture modulation

Discussion in 'Homework Help' started by Moskits8, May 5, 2015.

Why does Pspice says that nodes are floating? how to fix this problem with this schematic?

    In DC steady-state analysis PSpice treats all capacitors as a open circuit and inductors as a short circuit. And this is why the nodal voltage is floating.

    How to resolve this problem so I could simulate AC sweep with no errors !

    Add 1G resistor parallel with capacitors.

    Or skip DC point calculation.
    Also, why the hell is this a poll?

    There is no errors , but ""print parts"" shows that voltages and currents are zeroes!

    Change into Octave and 110 points per octave.

    Thanks for help!
    If i can ask one more question ?
    Im makilng parallel L circuit with coupling !
    And there is this error!
    ERROR Schematics 05:33PM Attribute Part K_Linear has no "L1" attribute
