Discussion
In this experiment, we used diodes to find the properties of them. It is a nonlinear element, so the data may have errors by little difference in voltage and current. We learned that junction diode is used to rectify the current and can be supposed to linear element with approximation3 using threshold voltage and bulk resistance. Zener diode is almost similar to junction diode, but it has lower breakout voltage and is used under reverse bias to limiting voltage as breakout voltage. In rectifying circuit, we just derived the VAVG and VP-P with theoretical calculation, but in real outcome in Table 4-X(b) has some difference with derived data. In rectifying circuit, we used diode to rectify the current, and threshold voltage should be considered to calculate V. Resistance in wires and R of diode made the error further. Thus, rectified output signals have smaller values compared with calculated values.
