Thank you! I changed the output part but the only pnp model that I find is this one. The desired pnp model is 2N2907, I can't fix this. I'm not familiar with SpiceYour PNPs are in the circuit backwards and there are missing connections on the lines labeled as outputs.
Yes, thank you now it is all done I thinkYou simply need to flip the symbol top-to-bottom. I don't know how you do this in LTspice since I don't use it, but there are probably mirror and rotate operations e.g. rotate 90 degrees twice then mirror
edit: there may be a mirror vertically operation which does what is required in one step
The given circuit names them as the same Vout. But I'm changing it in LTspice now. Thank you again.You should/must (?) name the two outputs differently. If they have the same name the simulator may consider them to be connected.
.tran 4mS (assuming that is correct syntax, which again I don't know) should be
.tran 4ms - lower case s for seconds, upper case for Siemens (unit of transconductance)
The original circuit names the differential output from the two outputs as Vout.The given circuit names them as the same Vout.
