pg. 38. Last two equations should read:

pg. 41. First part of second equation should read:

pg. 42. Last two equations should read as follows:

pg. 44. Last part of next-to-last equation for I_R(t) should read:

pg. 48. Figure 2.53, left graph. Caption at top left should read, “Low frequencies are less attenuated.” Caption at lower right should read, “High frequencies are greatly attenuated.”

pg. 49. Third and fourth sentences should read, “This reduction in impedance results in a leakage of input current through the capacitor to ground—the output voltage approaches zero. At low frequencies, the capacitor’s impedance is large; only a small amount of current passes through the capacitor to ground—the output voltage approaches the input voltage.”

pg. 49. The first part of the second equation should read:

pg. 49. For clarity, the last equation should include parentheses as follows:

pg. 53. The second line should read, “…you can design a filter that is capable of passing all frequencies except those near the…”

pg. 69. The first part of the first equation should read:

pg. 74. The equation for reflected power should read:

% reflected power =

pg. 75. The first equation should read:

pg. 75. The fourth line of text should read:

“For example, if Z₁=50W and Z₂=125W, then…”

pg. 75. The first part of the third equation should read:

pg. 75. The first line next to Impedance Transformer should read, “Here, a transformer is used to match the characteristic impedance…”

pg. 95. On the graph at the bottom of the page, the labels on the curves, I₁ and I₂, should be switched. Also, the label on the y-axis, I_in, should indicate the y-intercept of the upper curve and so should be placed at that intercept.

pg. 148. The last term of the first equation in the box at the upper left of the figure should be:

pg. 148. The first part of the equation at the bottom of the page should read:

pg. 150. The last term of the first equation in the box at the upper left of the figure should be:

pg. 151. The first equation would be better written as:

Gain

pg. 160. In the graph of Figure 4.49, the y-intercept should be labeled I_DSS

pg. 161. The third sentence should begin, “I_DSS is a constant…”

pg. 162. In problem 1, in the first line and also in the first equation, I_DDS should be replaced by I_DSS

pg. 165. In the equation on the bottom of the page, I_DDS should be replaced by I_DSS

pg. 170. In the two graphs at the bottom of the page, I_DDS should be replaced by I_DSS

pg. 171. In the equation for transconductance for a shorted gate, I_DDS should be replaced by I_DSS

pg. 173. In Problem 3, I_DDS should be replaced by I_DSS everywhere it appears

pg. 212. In the drawing on the left in Figure 5.28, pin 5 should read “collector 2” and the arrow in the transistor symbol to its left should point to the emitter of pin 6.

pg. 227. The last equation in the Integrator section should read:

pg. 272. The equation for duty cycle should read:

Duty cycle =
