Abstract

The performance of a dynamic element matching (DEM) flash digital to analog converter (DAC) can be improved by controlling the DEM DAC's interconnection network with a random signal that has a specific power spectral density (PSD) and a uniform probability distribution function (PDF). Many algorithms exist for generating a random signal with a white PSD and a uniform PDF, but there exists only one algorithm for generating a random signal with a specific PSD and a particular PDF. For DEM DAC applications, the random signal must be generated at the speed of the DEM DAC. However, a real time implementation of this existing algorithm is too computation intensive for a typical DEM DAC. In this thesis, an algorithm that constructs a uniformly distributed random signal with a specific PSD is developed. This uniformly distributed colored random signal is implemented using a finite state machine (FSM) and Linear Feedback Shift Registers (LFSRs).
