current vs. voltage curve for the 1n4148 diode. The DC sweep should be from 0.01 to 1.5 V and in steps of 0.01 V. The temperatures that should be simulated are -80, 0, 27, and 100

1. Circuit Diagram

2. Relevant Output Graphs

3. Analysis and explanation of the results

Solutions

Expert Solution

The solution is given below: (The simulation has been performed using LTSPICE)

1. Circuit Diagram:

3. The circuit diagram along with the output graphs is shown in the diagram above.

Diode current follows the relation I=Io [exp(eV/nKT)-1] where,

Io=Reverse saturation current

V=Applied voltage across the diode

n=(1 or 2) depending on the material of the diode

K=Boltzman's constant

T=Temp. in Kelvin.

Now, its very clear from the equation that increasing temp will result in decreasing current I. That's why in the simulated graph, with increasing temp, the current amplitude decreases.
