Table
| Metric | Value |
|---|---|
| Input signal | 10 mV peak, 1 kHz |
| Collector DC level | 48.9 mV |
| Collector average over 2 to 5 ms | 50.69 mV |
| Collector minimum | 41.58 mV |
| Collector maximum | 63.37 mV |
| Collector peak-to-peak swing | 21.79 mV |
| Input peak-to-peak swing | 20.00 mV |
| Voltage gain | -1.09 V/V |
- The stage is inverting, so the gain sign is negative.
- Reported voltage gain: approximately -1.09 V/V.
This biasing puts the transistor deep into saturation, so it is not behaving like a properly biased linear common-emitter amplifier.
- Base voltage: 0.728 V
- Collector voltage: 48.9 mV
So the waveform and gain above are valid for the exact circuit you requested, but this is an overbiased saturated stage, not a normal small-signal CE amplifier.
If you want, I can also simulate a properly biased version of the same 2N2222 amplifier and compare the gain and waveform.
