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

Using the Pull-In Voltage as Voltage Reference
2001The reproducibility of the pull-in voltage of a single side clamped free-standing beam has been investigated for application as a DC voltage reference. A 2 mm long beam has been fabricated in an epipoly process with, at the tip, poly-poly electrodes extending into the axial direction for electrostatic lateral deflection and a comb-drive operating in ...

Voltage Reference modification
Electronics and Communications, 2013Adaptation algorithm for saturation sensor of the n-p-n vertical output transistor model is proposed. This model algorithm implies convergence measuring natural IC results and complex (output transistor) + (sensor transistor) modeling. Critical model parameters are reveals and necessity of the error model average is proposed due to high non ideal ...

IEEE Journal of Solid-State Circuits, 1978
A method for developing a reference voltage in CMOS integrated circuits is described. The circuit uses MOS devices operating in the weak inversion region, as well as a bipolar device formed without process modifications. A brief description of this region of operation is given. Then, the principle of the suggested voltage reference is explained and the

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 ...

MEMS based voltage references: Dissertation
2006Voltage references are fundamental building blocks in many instruments like data logging systems, digital multimeters, and calibrators. State-of-the-art DC voltage references are large and expensive Josephson voltage standards, operated at cryogenic temperatures.
