I am working with a modified Howland circuit and I need to make sure that the constant output current does not increase over a certain limit. I wanted to know what the best way to do this was.
Since the Howland circuit is technically a voltage dependent current source I could have a overvoltage protection circuit before the signal enters the circuit. However, I am concerned that something could go wrong in the Howland circuit, that would lead to an unwanted increase in current. I am not so sure about this and wanted to discuss about this. Can someone help?
