Hi. The schematic of amplifier using BJT and the result is attached.
What I learned is that the beta, ratio of Ic/Ib, would be constant.
However, the ratio of Ic/Ib varies by the time.
I googled for this and found out that the beta varies with temperature and Ic but does it vary that much?
Ic is in range of 1.1mA~1.55mA from the simulation. How can I explain this situation?
