Question 57
INNAT2 marksNeeds review
In the figure shown, the diode current is given by
. V_D is the diode voltage in volts, T is the absolute temperature in Kelvin, α = 1.16 × 10⁴ K/V, and I_S = 10⁻¹⁵ A is the saturation current. The dc current source, opamp and the resistors are ideal, and are assumed to be temperature independent. The change in the output voltage (V_out) per Kelvin change in temperature is ________ mV (rounded off to one decimal place).
