General Errata
Errata other than A0E cross reference corrections and changes to the FPGA and microcontroller installation instructions.
Note: You can sort by page or by date, and you can print the list or download a pdf. Errata are corrected in successive printings, with approximate cutoff dates where applicable; so you can scroll down a date-sorted list to find needed corrections.

| 541 | Figure 12L.18 | The caption should read "At low VDS, JFET I-V behavior approximates that of a resistor. | We found it ourselves | 20250303 |
| 5 | Footnote 3 | Should read "... to produce ever more efficient ..." | Jeff Stribling | 20250417 |
| 461 | Figure 10L.3 | The upper (NPN) BJT is a MJE3055 and the lower (PNP) is a MJE2955 | We found it ourselves | 20250728 |
| 500 | Figure 11L.8 | The SCR part number is MCR218-4G (but the last digit "4" is the voltage and the "2" and "8" parts are fine - actually almost any SCR will work for this lab) | We found it ourselves | 20250728 |
| 1148 | Index | "VP01" should be "VP0106" | We found it ourselves | 20250728 |
| 1141 | Index | The IRLIB9343 MOSFET is no longer used in the book. Please ignore this index entry. | We found it ourselves | 20250728 |
| 33 | Figure 1L.10 | The figure shown is incorrect. Here is the correct figure: | Florian Mintgen | 20250731 |
| 556 | Figure 13N.3(a) | The pinout for the TSTS7100 IR LED is reversed. The anode is nearest the tab, Here is the correct figure:  | Kathryn Ledbetter | 20251015 |
| 558 | §13L.2.1 | The input impedance on the LMC555's control input is 66k (not 33k). | Kathryn Ledbetter | 20251015 |
| 947 | 24L.3.4 | To see the DAC output sinewave with a 1mSec delay, you may have to look directly at the output of the LM386 (pin 5), as the frequency may be below the cutoff frequency of the 100uF blocking capacitor and speaker. | We found it ourselves | 20260904 |
| 284 | Figure 6L.10 | Students in the Fall 2026 class were confused by the use of an analog inverter block diagram in the schematic. This updated figure should be clearer. 6L.010 Phase shifter, basic design | David Abrams | 20263029 |
| 285 | 6L.8 | Students in the Fall 2026 class were confused by the instructions in the last full paragraph on the page to "... reconnect the right side of the feedback resistor to the push–pull output (as proposed near the end of Chapter 6N)..." It should be changed to "... reconnect the right side of the feedback resistor to the push–pull output (as shown in Figure 6N.20 as the SMART connection)..." | David Abrams | 20260929 |
| 282 | Figure 6L5 | Students in the Fall 2026 class were confused by the instruction in 6L.3.2 to "treat this [resistor] (perversely) as part of the follower, and look at Vout ..." We have updated the figure to show where to measure Vout.  Figure 6L.5 Measuring Rout – and effect of feedback on | David Abrams | 20261008 |
| 553 | Last paragraph before Sec. 13N.1.4 | "...up to about 3 mrkHz..." should be ...up to about 3 kHz..." | David Abrams | 20261015 |
