Let's Get to the Sweet Spot
For any of the above circuit types and devices, if you start with reasonable textbook values for the circuit, you will get reasonable performance. If you start to play with the values a little bit, you will find that the performance changes for better or worse. Often you will find a combination of voltage and resistor values which give a lot better than the generic performance. That's the sweet spot.

This technique is often referred to as load-line cancellation. It is called that because the range of the device's operation sits on a line in the transfer curve, and the particular shape and position of that line results in minimum distortion |
