I'm trying to do a simple 1 kHz, 1 V p-p sine wave amplification circuit using a TL071 or similar op-amp. The simulation is currently in LTSpice.
I've biased the VCC to half to try to achieve a good voltage swing but the waveform clips; it seems that the op-amp is amplifying my DC bias also.
I don't expect this op-amp to be rail-to-rail, of course.
First, here are the output waveforms:
V(out) is the small output signal, red is the AC sine wave, green is the biased waveform, centered at VCC/2.
Here's my circuit:
Any help? I'm new to this world of op-amps and struggling a bit.
