Current Sources and Voltage References provides fixed, well-regulated levels of current or voltage within a circuit. These are two of the most important “building blocks “ of analog circuits, and are typically used in creating most analog IC designs. Part 1 shows the reader how current sources are created, how they can be optimized, and how they can be utilized by the OEM circuit designer. The book serves as a “must-have reference for the successful development of precision circuit applications. It shows practical examples using either BJTs, FETs, precision op amps, or even matched CMOS arrays being used to create highly accurate current source designs, ranging from nanoAmps to Amps. In each chapter the most important characteristics of the particular semiconductor type being studied are carefully reviewed. This not only serves as a helpful refresher for experienced engineers, but also as a good foundation for all EE student coursework, and includes device models and relevant equations. Part 2 focuses on semiconductor voltage references, from their design to their various practical enhancements. It ranges from the simple Zener diode to today’s most advanced topologies, including Analog Devices’ XFET® and Intersil’s FGATM (invented while this book was being written). Over 300 applications and circuit diagrams are shown throughout this easy-to-read, practical reference book. * Discusses how to design low-noise, precision current sources using matched transistor pairs. * Explains the design of high power current sources with power MOSFETs * Gives proven techniques to reduce drift and improve accuracy in voltage references.

Voltage references represent important VLSI structures, having multiple appli- tions in analog and mixed-signal circuits: measurement equipment, voltage re- lators, temperature sensors, data acquisition systems, memories, or AD and DA converters. Operating as a subcircuit in a complex system, an important requi- ment for this class of circuits is represented by the possibility of implementation in the existing technology, using the available active and passive devices. The most important performances of a voltage reference circuit are represented by temperature behavior, power supply rejection ratio, transient response and, for the latest designs, by low-power low-voltage operation. Depending on the load - quirements, the output of the circuit can be regulated or unregulated. In order to reduce the sensitivity of the reference voltage with respect to the supply voltage variations, modi?ed cascode structures can be implemented, a trade-off between line regulation and low-voltage operation being necessary in this case. A large bandwidth of the voltage reference improves the transient behavior of the circuit, implying also a good noise rejection. Referringtothe possibilities ofimplementinga voltagereferencecircuit,two d- ferent approaches could be identi?ed: voltage-mode and current-mode topologies, being also possible to design a mixed-mode voltage reference.

A practical overview of CMOS circuit design, this book covers the technology, analysis, and design techniques of voltage reference circuits. The design requirements covered follow modern CMOS processes, with an emphasis on low power, low voltage, and low temperature coefficient voltage reference design. Dedicating a chapter to each stage of the design process, the authors have organized the content to give readers the tools they need to implement the technologies themselves. Readers will gain an understanding of device characteristics, the practical considerations behind circuit topology, and potential problems with each type of circuit. Many design examples are used throughout, most of which have been tested with silicon implementation or employed in real-world products. This ensures that the material presented relevant to both students studying the topic as well as readers requiring a practical viewpoint. Covers CMOS voltage reference circuit design, from the basics through to advanced topics Provides an overview of basic device physics and different building blocks of voltage reference designs Features real-world examples based on actual silicon implementation Includes analytical exercises, simulation exercises, and silicon layout exercises, giving readers guidance and design layout experience for voltage reference circuits Solution manual available to instructors from the book’s companion website This book is highly useful for graduate students in VLSI design, as well as practicing analog engineers and IC design professionals. Advanced undergraduates preparing for further study in VLSI will also find this book a helpful companion text.

IN THE OPERATION OF THE MODEL MAGNET FOR CYCLOTRON DESIGN STUDIES THE NEED ARISES FOR AN ULTRA STABLE VOLTAGE REFERENCE SUPPLY. It is necessary that the supply be capable of delivering 1.2 to 1.4 milliamperes to a 1100 ohm load. The voltage reference should be stable to 0.005% over a day's time, operating essentially at room temperature with a maximum variation of 5 C.A device was constructed that used two voltage reference tubes and three zener diodes to obtain this regulation. The voltage supply was placed in an environment in which it was to be used and was monitored for over a month. The standard deviation of the volttage measurements made was 0.0017% with the maximum deviation observed being 0.0023% (Author).

A new design approach for high performance voltage references has been developed. This approach exploits the inflection point property of a first-order voltage reference where the temperature derivative is zero at a temperature in the range of interest. By creating an ordered family of these references with the corresponding inflection points distributed across a wide temperature range and using a temperature trigger to continuously transition between these references, a highly accurate wide temperature range voltage reference is realizable. The resultant voltage references that have an output voltage that has been stabilized to temperature changes in the environment are termed "environ-stabilized" voltage reference. The implementation of an environ-stabilized voltage reference using this approach is verified through both transistor level and behavioral simulations. The implementation of a 3-family reference predicts an error voltage of less than 180[mu]V for a temperature between - 40°C and 100°C. This is equivalent to a temperature coefficient of 1.06ppm/0C. Further reductions in the equivalent temperature coefficient are possible if the number of members in the family is increased. The performance degradation of the environ-stabilized voltage references due to process variations was also studied. A self-calibration scheme has been introduced to correct errors introduced by process variations. The result suggests the environ-stabilized reference approach can be used for the realization of highly accurate voltage references that operate over a wide temperature range throughout a wide range of the process variations.
