{"product_id":"9780792372110","title":"Analog Test Signal Generation Using Periodic ΣΔ-Encoded Data Streams","description":"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.
