PSPICE help needed: plotting load voltage of a Class-B amp

Hello,

I'm having trouble getting the right output graph for the following circuit (class-b amplifier w/ darlington pair).

The correct output is supposed to be a nice sin wave with some distortion (the problems objective is to show it to you visually)... but I'm not getting the right plot. I've attached my results also.

I'm not sure where my slip-up is :confused: -- I've checked everything so I'm assuming that it's something very minor and involves PSPICE (I'm still getting accustomed to it).

Can anybody help me out? I'd REALLY appreciate it. Thank you for your time.

Best Regards,
Arthur

I got the following error when I put the circuit in exactly as shown:

Expecting keyword STIMULUS, saw V.|

STIMULUS has to do with the configuation files so...crap.

So it's not supposed to be a sin wave?

I'm still getting a transient looking wave, like a capacitor type output, and not a sin wave which I thought was the correct output.

Thanks for your replies!

Check your print step rate. I didn't really zoom in on the output. It "kind of" looked sinusoidal. But it wasn't a smooth wave by any means.
