RESISTOR STRING DIGITAL TO ANALOG CONVERTOR WITH DIFFERENTIAL OUTPUTS AND REDUCED SWITCH COUNT |
摘要 |
<p>Resistor string DAC's are known to utilize lots of area and slow in data conversion due to the large utilization of switches. The problem becomes worse when differential outputs are required in the conversion process. This invention describes a N-bit DAC architecture utilizing a substantially lower number of switches through a unique placement of tap-points in the resistor string and decode logic. Differential outputs share the same set of switches through 2 levels of decoding.</p> |
