*6.42 In the circuit shown in Fig. P6.42, current source I is 1.1 mA, and at 25°C v BE = 680 mV at i E = 1 mA. At 25°C with β=100, what currents flow in R 1 and R 2 ?What voltage would you expect at node E? Noting that the temperature coefficient of v BE for I E constant is −2 mV/°C, what is the TC of v E ? For an ambient temperature of 75°C, what voltage would you expect at node E? Clearly state any simplifying assumptions you make.
