Abstract [en]

To design a high-speed flash D/A converter with high resolution we need to keep the glitch noise within acceptable levels. The current practice is to use a segmented converter structure where we can trade off hardware complexity and glitch performance by selecting a proper number of most significant bits to be thermometer coded. For the remaining least significant bits (LSB) binary-scale are used. A recently proposed alternative to this method is to design a converter with linearly increasing weights, i.e., 1 LSB, 2 LSB, 3 LSB,... . In this paper, we propose two new converter structures that both have a dual linear-coded source matrix operating in parallel with the original linear-coded source matrix. Simulations show that we can expect up to 30% better glitch performance for one of the proposed structures, assuming signals with moderate transitions. However, for signals with large transitions there is no significant improvement.
