Question

Silicon diodes can be used a temperature sensors-to use a diode to measure temp sensor, it is typically forward biased and fed with a constant current source (11 below). The output voltage Va is monitored as a function of temperature. Assume that the diode is run such that I = lo exp(qVa/kT), and that the intended range of use is between 0 and 100 deg C. With I as an input variable, establish a program or spreadsheet to compute Va versus T from 0 to 100deg C. Make a plot assuming I1 = 1e-4 amps. 11 Va I 1 D1 D 사

Answer 1

Silicon diodes can be used as temperature sensors by forward biasing them and monitoring the output voltage as a function of temperature. A program or spreadsheet can be used to compute Va versus T using the equation I = I0 * exp(qVa/kT), where I is the input variable. With I1 = 1e-4 amps, you can plot Va versus T.

Step-by-step explanation:

A silicon diode can be used as a temperature sensor by forward biasing it and feeding it with a constant current source. The output voltage, Va, can then be monitored as a function of temperature. To compute Va versus T from 0 to 100°C, you can establish a program or spreadsheet using the equation I = I0 * exp(qVa/kT), where I is the input variable. Assuming I1 = 1e-4 amps, you can plot Va versus T.
