actually i cannot understand about.
why the base bias circuit has poor stability in relation to β variation.
and one more question
collector-feedback bias circuit provides bias stability with respect to temperature fluctuations.
i already simulation two graph ICQ versus Temperature and ICQ versus β used the multisim to do it~ but in the graph in lineary function,but i still cannot understand what is this two question theory ,i dunknow how to explain about very reasonable ~someone else got any suggestion on this two question ~mind to help me ?....thank.
