I made this circuit and the output signal wasn't really what I was expecting to be.
This is class A amplifier (both Q1 and Q2 conducting both negative and positive half cycles). I was only curious how the signal from V1 is buffered to the output and I am already (at this point) insecure about its operation.
Here is the measurement of a signal I scoped:
As can be seen, there is a "double-amplitude" signal at the point where I probed the circuit.
- Is this the consequence of Q1 and Q2 constantly conducting the signal?
