Following on from my last question Cascaded BJT Amplifier Load - I'm trying to understand what it is (via math or otherwise) that causes the input signal to appear malformed when the output of the signal starts 'clipping'
Looking at my circuit:
Am I right in saying that for the output at the collector (V(n002)):
- The clipping at the high end is because it cannot swing above Vcc?
- the clipping at the low end is because the voltage at the collector (V(n002)) cannot go below the voltage at the transistors emitter (3.18V)?
Then my main question is - Why is it that the limits of the biasing/BJT cause a change to the input signal when measured at the base of the BJT (V(n005)?
