Genetic diversity of small yellow croaker Larimichthys polyactis revealed by AFLP markers
2009
A first current cell group of an digital-to-analog converter has a first set of current cells which individually turn on and off in response to respectively input digital signals. A second current cell group of the analog-to-digital converter has a second set of current cells which respectively correspond to the first set of current cells and which individually turn on and off in response to respectively input digital signals such that an on/off state of each of the first set of current cells is opposite an on/off state of each corresponding one of the second set of current cells. The first set of currents cells are connected in parallel between a first power supply voltage and a first node, and the second set of currents cells are connected in parallel between the first node and a second power supply voltage. An output circuit generates an analog signal from either the current flowing from the first current cell group to the first node, or the current flowing from the first node to the second current cell group.
