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
MT-087: Voltage References - Analog
www.analog.comThe bandgap reference technique is attractive in IC designs because of several reasons; among these are the relative simplicity, and the avoidance of zeners and their noise. However, very important in these days of ever decreasing system supplies is the fundamental fact that bandgap devices operate at low voltages, i.e., <5 V.

ADC The characteristics of BJT have proven the most well-defined quantities providing positive and negative TC kT/q has a positive temperature coefficient

A precision external voltage reference has a much lower temperature coefficient, thermal hysteresis, and long-term drift than an on-chip band-gap voltage reference; therefore, in
