| Jun 8, 2016 at 17:18 | comment | added | The Photon | Changing the question after someone has taken time to answer just makes the site less useful for future readers, and discourages people from answering your question. If you come up with new questions after getting an answer to your posted question, consider making a new question post. | |

| Jun 6, 2016 at 16:29 | comment | added | The Photon | Now I read the patent (esp. paragraph 0024) and I am pretty sure you need to reverse the polarity of your input source to make the circuit work as expected. | |
| Jun 6, 2016 at 16:20 | comment | added | The Photon | What happens if you reverse your input current? Also, you might need to use "real" current sources (current mirrors) rather than ideal current sources for I2 and I3 to avoid this circuit going crazy. Think about what happens if I1 produces 15 mA. How is KCL satisfied without something else going nuts (like a didoe going into reverse breakdown)? | |
| Jun 6, 2016 at 14:09 | comment | added | George Herold | Why are you doing this? What breaks if the current is greater than 5 mA? (You could limit the opamp output voltage.) | |
