ABSTRACT:
A multi-stage digital to analog converter with increased speed and enhanced accuracy. Multiple resistor ladders are interconnected through switches with the first resistor ladder converting the most significant bits and successive ladders converting lesser significant bits. The resistance values of the resistors of each ladder are greater than those of the preceding ladders in order to minimize inaccuracies due to loading. A monolithic fabrication technique includes a common resistor biasing scheme to switch the voltage across parasitic capacitances associated with the resistors in each ladder in common mode, thereby increasing the converter speed.
