2011-12-03 Low Voltage Joule Thief – TN0702 MOSFET

In Jan 2009 I collaborated with Quantsuff and we tried different designs for a low voltage Joule Thief.  The conventional silicon BJT Joule Thief (bipolar junction transistor) has a base to emitter forward voltage of about 0.55 to 0.6 volts, so if the supply is below this voltage it will not start.  But once it
