Under Douglas: Change "Lenng" to "Leung"
Fig. 3.1-1 – To remove any confusion by the use of arrows to designate potentials, in
this figure the arrow goes from the negative potential to the positive potential.
Paragraph 1, line 6: “Thus, a value for CBX of 12.1 F and 9.9 F results…”
→ ”Thus, a value for CBX of 12.1fF and 9.9fF results…” (Thanks to Volker
Typke)

Eq. (4.6-26): Replace “VBE2” with “VEB2”.
Prob. 4.3-1: Remove "Ignore the body effect."
Prob. 4.3-4: At the end add "Ignore the body effect to simplify calculations."
Prob. 4.6-5: Change first sentence to "If the bipolar transistor in Fig. 4.6-8(a) is a
true vertical bipolar transistor (can be......"
Fig. 5.2-9: Right "gm1vgs1" in both figures should be "gm2vgs2"
Prob. 5.2-6: Add before the period of the last sentence “and VDD = 2.5V”
Prob. 5.2-10: Change “Assume that ISS is 50µA.” to “Assume that ISS is 50µA and
all W/L=1.”
Line 6 from top: Replace “…M2 is on and M1 is off.” with “…M1 is on and M2 is
off.”
Prob. 6.5-1: Delete the sentence “Design the value of R to keep the source-drain
voltage of M3 and M4 to be equal to Vds(sat).”
Fig. 7.4-2 There should be a “vi1” next to the gate of M1 in Fig. 7.4-2.
