www.seas.ucla.eduLow-Voltage Bandgap References The basic bandgap expression, VV BE +17.,2 T takes on a value of about 1.25 V at T = 300K, defying direct implementation in today’s low-voltage technologies. We describe one low-voltage example and refer the reader to [10] and [11] for others. For a low-voltage bandgap reference to have a zero TC, it must produce an
