06.03.1 Chapter 06.03 Linear Regression-More Examples Computer Engineering Example 1 To simplify a model for a diode, it is approximated by a forward bias model consisting of DC voltage, d V , and resistor d R . Below are the current vs. voltage data that is collected for a small signal. Table 1 Current versus voltage for a small signal. V (volts) I (amps) 0.6 0.01 0.7 0.05 0.8 0.20 0.9 0.70 1.0 2.00 1.1 4.00 The I vs. V data is regressed to 0 1 B V B I . Once 0 B and 1 B are known, d V and d R can be computed as 1 0 B B V d and 1 1 B R d Find the value of d V and d R . Solution Table 2 shows the summations needed for the calculation of the constants of the regression model.
