hello, I have implemented the circuit shown in the image attached with this post. When i run the circuit it gives me and error i.e.
"ERROR -- Convergence problem in transient bias point calculation".
The simulation window shows these messages:

ERROR -- Convergence problem in transient bias point calculation


  Last node voltages tried were:

 NODE   VOLTAGE     NODE   VOLTAGE     NODE   VOLTAGE     NODE   VOLTAGE


(N00123)    4.2872 (N00130)    1.5484 (N00134)    2.9775 (N00210)    4.2872

  These supply currents failed to converge:

    I(V_V1)                   =   -10.00GA  \   -10.00GA

Are you joking? Obviously the schematic circuit doesn't belong to the netlist which has e.g. 4 transistors and three voltage sources.
