Reference no: EM131018920

Consider the thermal shutdown circuit shown in Fig. At 25°C, Z1 is a 6.8-V zener diode with a TC of 2 mV/°C, and Q1 and Q2 are BJTs that display VBE of 0.7 V at a current of 100μA and have a TC of -2 mV/C. Design the circuit so that at 125°C, a current of 200μA flows in each of Q1 and Q2. What is the current in Q2 at 25°C?
