Demonstrates a method by which high-precision analog waveforms can be generated on chip, with minimal silicon overhead, using a digital oversampling-based oscillator, for use in testing digital integrated circuits (ICs). Introduces the testing problem and conventional signal generation techniques, and details the method and equipment and its application in multi-tone signal generation and testing. Also discusses piece-wise linear waveforms and delta-sigma modulation techniques. Includes b&w diagrams and appendices of source code. Annotation copyright Book News, Inc. Portland, Or.

Analog Signal Generation for Built-In-Self-Test (BIST) of Mixed-Signal Integrated Circuits is a concise introduction to a powerful new signal generation technique. The book begins with a brief introduction to the testing problem and a review of conventional signal generation techniques. The book then describes an oversampling-based oscillator capable of generating high-precision analog tones using a combination of digital logic and D/A conversion. These concepts are then extended to multi-tone testing schemes without introducing a severe hardware penalty. The concepts are extended further to encompass piece-wise linear waveforms such as square, triangular and sawtooth waves. Experimental results are presented to verify the ideas in each chapter and finally, conclusions are drawn. For those readers unfamiliar with delta-sigma modulation techniques, a brief introduction to this subject is also provided in an appendix. The book is ideal for test engineers, researchers and circuits designers with an interest in IC testing methods.
