    Hi. am new to pspice and am trying to get oscillation from this Colpitts Oscillator circuit [​IMG]

    the problem is that c5 output isnt connected to anything so simulation wont work ... this can be easy to solve in multisem but i couldnt do it in Pspice .


    if you see any other mistakes in my design feel free to tell me :D

    No power supply. Look at all the node voltages.

    Connect C2 to some resistive load to ground. Try 1K to 1meg.
