Hi All,
I have been reading through the article and there's one particular resistor value that I can't be sure that I understand. In page 6 of the article, Nelson mentioned that R5 is a 100 ohm resistor, which sets the output impedance of the circuit together with R3. However, on the schematic, R5 is marked as 33.2K. Is there an error in the schematic?
Best regards
Liu

It's most likely a typo as the first version has R5=100R.

The current schematic is correct.

Thanks Ben. Would the output impedance remain as 400 ohms in this case?
Thanks Max. I am sorry. I missed the few posts there, and all the answers to my questions are there

So it's probably a typo as mentioned by Ben. It should be R4 instead of R5, which is 332ohms. If we would like to keep it the same as previous version we can also change it to 100 ohms.
