1 nanoamp Current Source with No Resistors Using Self Cascode MOSFET

Note the 500M Ohm resistor is only to test the current reference.  It would be replaced by your application circuit.

Ultra Low Current Band Gap References Using NanoAmps of Current with Good MonteCarlo Results

If you need a voltage reference when doing energy harvesting it is very helpful have a band gap reference that uses very little current.  This topology uses “Self Cascode Mosfet”  abreviated as SCM.  The LTSPICE design uses 4.5 nano Amperes and outputs a 0.6 Volt reference voltage.
