NOISE LIMITATION OF A SIGNAL DEPENDENT MULTIBIT DIGITAL TO ANALOG SIGNAL CONVERSION |
摘要 |
Several methods and a system of noise limitation of a signal dependent multibit digital to analog signal conversion are disclosed. An exemplary embodiment provides a method that includes receiving an output of a multibit analog to digital circuit of a continuous time sigma delta converter. The method further includes limiting a noise generation by adaptively selecting a digital to analog converter element out of a plurality of digital to analog converter elements in accordance with an input signal magnitude. In addition, the method includes implementing a selected digital to analog converter element to generate an analog signal.
