How can you increase your confidence in designing a bias circuit?
Answer:
You can always use some SPICE program to simulate your design. Keep in mind that it is a simulation, only, and that there will be differences in the real circuit, but you can 'play' with different values in the bias circuit simulation to see what the basic effects are on the overall circuit.

Practice. Practice....... Years in Electronic Engineering Technology.
improve your understanding behind the methodology of the design. How are the values calculated? What happens if the values deviate 10%? What happens over temperature? Calculate the worst case min and max operating pointfor the active device. Is is acceptable?
Work through different examples, which have different requirements, which will lead to different solutions.
