Question:

For the circuit of Fig. 4.64, find the value of W/L for which dV_GS/dT = 0 at 25 °C. Assume that the threshold voltage falls 2 mV for each 1°C increase in temperature. Also, assume that the mobility temperature dependence is given by (4.243) with n = 1.5. Finally, use Table 2.4 for other parameters at 25 °C, and let I = 200 µA.
