3/2 Dependent Sources and MOSFETs

         The purpose of this lab is to observe how the dependent sources circuit work and determine what types of dependent sources is this.

1. Diagram of circuit:
    This photo shows that we measured the value of resistance.

This photo shows how we connect the entire circuit.

According to all the data we got from the measurement, we have this graph that shows the relationship between current and voltage.

Based on the graph, we found that the MOSFET threshold voltage is  around 0.68 V.

4. This is a dependent source because when we increase the value of voltage, the value of current also increases. Therefore, this is a depend source.

5.
According to this graph, the value of g is 0.8923.

Summary
      In today's class, we learned the concept of KCL and KVL circuit. The key point of KCL circuit is that the total current through one node have to be 0. The same as the KVL which is the total voltage through one node has to be 0. The following photos are some examples we did during the lecture time:
