Discuss the below:
Q: In the circuit shown in Fig. current source I is 1.1 mA, and at 25°C vBE = 680 mV at iE = 1 mA. At 25°C with β=100, what currents flow in R1 and R2? What voltage would you expect at node E? Noting that the temperature coefficient t of vBE for IE constant is -2 mV/°C, what is the TC of vE? For an ambient temperature of 75°C, what voltage would you expect at node E? Clearly state any simplifying assumptions you make.
