Design ofBandgap Reference and CurrentReference ...

Design of bandgap Reference and Current Reference Generator with Low Supply voltage Dong-Ok Han , Jeong-Hoon Kim, Nam-Heung Kim WS lab, Central R&D Institute of Samsung Electro Mechanics, 314, Maetan3-Dong, Yeongtong-Gu, Su-won, Gyunggi-Do, Korea *Email: Abstract PM, PM, A Design of a CMOS bandgap voltage Reference and Reference current generator is described and the measurement results are presented in wide temperature range. Using by the resistive subdivision method, the Reference circuit is operated with low supply. The R3. measured Reference voltage is 630mV and temperature coefficient of bandgap Reference is 29ppm/ C from -10 C to 100 C with supply voltage . The Reference B3. current of generator which uses the Reference voltage is in that temperature range. 1.

In 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.

The development of low voltage (<5 V) references based on the bandgap voltage of silicon led to the introductions of various ICs which could be operated on low voltage supplies with good TC performance. The first of these was the LM109 (Reference 1), and a basic bandgap reference cell is shown in Figure 2.

Low-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

As long as the voltage is much larger than kT/q, the power output P = VI is P = V 0.036−4×10−6 exp V 0.0518 +400×10−12 exp V 0.0259 . (1) The easiest way to determine what value of V maximizes this power is to use EXCEL to tabulate P as a function of V and observe which value of the voltage leads to the largest P. The result is
