The book begins with an 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 analogue 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 should be useful for test engineers, researchers and circuits designers with an interest in IC testing methods.
