An NMOS temperature-stable voltage reference, affording - in breadboard results - a temperature drift of less than 6 PPM/°C, will be described. Calculations show that less than 2 PPM/°C can be achieved with proper choice of device geometries.

A new voltage reference generator for dynamic voltage restorer
2015 IEEE 24th International Symposium on Industrial Electronics (ISIE), 2015Dynamic voltage restore (DVR) is a well established power device able to compensate voltage disturbances, in especial voltage sags and swells, in the power system. Its main goal is to protect sensitive loads against these disturbances. For this purpose, the precise computation of the DVR compensation voltage reference is a important issue.

A CMOS voltage reference for ultra low-voltage applications
2005 12th IEEE International Conference on Electronics, Circuits and Systems, 2005This work describes a CMOS voltage reference using only resistors and transistors working in weak inversion, without any bipolar transistors. The circuit operation is similar to bandgap references, but the voltage reference is given by the threshold voltage of an NMOS transistor. The circuit was implemented in a standard 0.35 mum TSMC CMOS process. The

Low Voltage CMOS Current and Voltage References without Resistors
2007 IEEE International Symposium on Circuits and Systems, 2007The authors describe low voltage current and voltage references which only use MOSFETs in strong inversion and pnp substrate transistors; both the references exhibit very good performance in terms of power supply rejection and do not require compensation capacitances; the minimum supply voltage is about 0.8V for the current reference and 1.2V for the ...

Threshold voltage based CMOS voltage reference
IEE Proceedings - Circuits, Devices and Systems, 2004The paper describes a CMOS voltage reference design that uses the temperature dependence of NMOS and PMOS threshold voltages to form a temperature-insensitive reference. No diodes or parasitic bipolar transistors are used. The circuit architecture accommodates a wide range of output voltages. A test chip is fabricated using a 0.5 /spl mu/m CMOS process.

Many electronic systems need compact, portable voltage regulator and reference elements capable of stable operation over a wide range of environmental conditions. All circuits are, to a greater or lesser extent, sensitive to supply voltage variations. In extreme cases these may cause catastrophic malfunction of the circuit ; more usually the accuracy ...

CMOS voltage reference based on threshold voltage and thermal voltage
Analog Integrated Circuits and Signal Processing, 2009A fully CMOS based voltage reference circuit is presented in this paper. The voltage reference circuit uses the difference between gate-to-source voltages of two MOSFETs operating in the weak-inversion region to generate the voltage with positive temperature coefficient. The reference voltage can be obtained by combining this voltage difference and the

Temperature compensated CMOS voltage reference
2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003A fully integrated digitally calibrated voltage reference is presented. This reference is mostly digital, making use of a simple low-pass RC filter as the only analog component. The proposed circuit can be used for single ended as well as differential applications.

Reference voltage is a ruler that is used by the ADC to weight the analog input. Accurate reference voltage plays an important role in the high-speed and high-resolution data conversion. In this chapter, we focus on the reference voltage buffer design. First, the traditional narrow-bandwidth buffer and wide-bandwidth buffer are depicted.
