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.
