Your friend Lynn Year looks at this circuit and says this can be modeled as a voltage controlled current source. Since you are learning about this in 10A she comes to you for help in figuring it out. You model the circuit as shown in figure 9. You learned that to find g you need to incrementally move Vin and measure Ic (tastes like a derivative!). So what is the transconductance g, at the operating point? Hint: Think orders of magnitude and what you can ignore to make your life easier. i. =0 out 14 g.v in in V. in Figure 9: Nonlinear Circuit out 0 1 2 3 4 5 6 0 7 8 9 10 11 12 13 14 15 16 17 18 19 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 Figure 6: Nonlinear Device Characteristics 28 Your friend Lynn Year looks at this circuit and says this can be modeled as a voltage controlled current source.
