Dear Ti Precision Lab,
I am studying the TI precision Lab Low distortion design Part 2. I have three questions here and hope someone could help.
(1) On Page 9, It is clearly stated running over crossover region will contribute to DC offset change, this will distort the signal and introduce harmonics. But how about " shift in AC parameters" what does it mean?
(2) On Page 11, the instructor determines the crossover region from the upper band of the common mode voltage range, saying that the crossover region at V- 2V. How could we determine crossover region, is that the same as the upper common mode range?
(3) On the summary page, Page 16, why inverting amplifier has low input crossover distortion and can prevent common mode impedance effects than non-inverting amplifier?
Thanks,
B.F
