This book was released on 2012-12-06 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analog Test Signal Generation Using Periodic SigmaDelta-Encoded Data Streams presents a new method to generate high quality analog signals with low hardware complexity. The theory of periodic SigmaDelta-encoded bitstreams is presented along with a set of empirical tables to help select the appropriate parameters of a bitstream. An optimization procedure is also outlined to help select a bit sequence with the desired attributes. A large variety of signals can be generated using this approach. Silicon implementation issues are discussed with a specific emphasis on area overhead and ease of design. One FPGA circuit and three different silicon implementations are presented along with experimental results. It is shown that simple designs are capable of generating very high precision signals-on-chip. The technique is further extended to multi-bit signal generation where it is shown how to increase the performance of arbitrary waveform, generators commonly found in past and present-day mixed-signal testers. No hardware modifications are required, only the numbers in memory are changed. Three different calibration techniques to reduce the effects of the AWG's non-linearities are also introduced, together with supporting experimental evidence. The main focus of this text is to describe an area-efficient technique for analog signal generation using SigmaDelta-encoded data stream. The main characteristics of the technique are: High quality signals (SFDR of 110 dB observed); Large variety of signals generated; Bitstreams easily obtained with a fast optimization program; Good frequency resolution, compatible with coherent sampling; Simple and fast hardware implementation; Mostly digital, except an easily testable 1-bit DAC and possibly a reconstruction filter; Memory already available on-chip can be reused, reducing area overhead; Designs can be incorporated into existing CAD tools; High frequency generation.

Book excerpt: This book describes techniques that can reduce mechanical-stress-induced inaccuracy and long-term instability in chips. The authors also show that the piezojunction effect can be applied for new types of mechanical-sensor structures. Thermo-mechanical stress is induced when packaged chips cool down to the temperature of application.

This book was released on 2006-04-18 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on my doctoral thesis at the Helsinki University of Technology. Several different projects during five years guided me from the basics of the RF IC design to the implementations of highly integrated radio receiver chips. Sharing time and effort between IC and system issues is not always straightforward. I have been lucky to follow both topics and share experiences with diligent and enthusiastic people having different specialities. As a result, this book will cover a wide range of different topics needed in the design of highly integrated radio receivers. Experiences from the first receiver prototypes for the third generation cellular systems form the basis of this book. Most of the issues are directly related to the early proposals of European and Japanese standardization organizations. For example, the chip rate was originally set to 4. 096 Mcps in a wide-band CDMA channel. I have kept that number in the book in most of the examples although it has been later changed to 3. 84 Mcps. I hope that the readers will accept that and the possible other incompabilities to the latest specifications. At least in the research phase the changes even in the most essential requirements are definitely not a rare incident and IC designers should be able to react and modify their designs as soon as they can.

Download or read book Design of High Performance CMOS Voltage Controlled Oscillators written by Liang Dai and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design of High-Performance CMOS Voltage-Controlled Oscillators presents a phase noise modeling framework for CMOS ring oscillators. The analysis considers both linear and nonlinear operation. It indicates that fast rail-to-rail switching has to be achieved to minimize phase noise. Additionally, in conventional design the flicker noise in the bias circuit can potentially dominate the phase noise at low offset frequencies. Therefore, for narrow bandwidth PLLs, noise up conversion for the bias circuits should be minimized. We define the effective Q factor (Qeff) for ring oscillators and predict its increase for CMOS processes with smaller feature sizes. Our phase noise analysis is validated via simulation and measurement results. The digital switching noise coupled through the power supply and substrate is usually the dominant source of clock jitter. Improving the supply and substrate noise immunity of a PLL is a challenging job in hostile environments such as a microprocessor chip where millions of digital gates are present.
