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. \u003cbr\u003e  The main focus of this text is to describe an area-efficient technique  for analog signal generation using SigmaDelta-encoded data stream.
