Constant Current Source
Allow make the following ammendment: The testing I did was using an "Improved Howland Current Pump" configuration with a 15 V supply and impedances of less than 100K (max 150 uA). I wasn't testing at the upper end of my impedance limit. However, even using resistances much lower...- rmcdermo

Constant Current Source
Please help! I'm trying to build a constant current source that will drive between 5 uA and 200 uA through a variable impedance (50 kohms to 500 kohms) to ground. Once wired, the system will not need to be adjusted. (Multiple set-ups for different current levels will be made). I need an...- rmcdermo
