Design ofBandgap Reference and CurrentReference ...
web.mit.eduIn this paper, a precise linear CMOS bandgap voltage reference was designed by using resistive subdivision method as described in [4]. A temperature compensated reference current generator was designed by bandgap reference voltage. The voltage reference have been designed and optimized for low supply voltage and wide temperature range. 2.
TL431 - Programmable Precision References
www.onsemi.comamp circuitry. The 2.5 V reference makes it convenient to obtain a stable reference from 5.0 V logic supplies, and since the TL431A, B operates as a shunt regulator, it can be used as either a positive or negative voltage reference. Features • Programmable Output Voltage to 36 V • Voltage Reference Tolerance: ±0.4%, Typ @ 25°C (TL431B)
