ARCHITECTURE COMBINING A CONTINUOUS-TIME STAGE WITH A SWITCHED-CAPACITOR STAGE FOR DIGITAL-TO-ANALOG CONVERTERS AND LOW-PASS FILTERS
摘要
A digital to analog converter (DAC) includes a first continuous-time stage that receives an input signal associated with a digital signal and performs continuous-time digital-to-analog conversion operations on the input signal. The first continuous-time stage outputs a first output signal. A second switched-capacitor stage receives the first output signal and performs switched-capacitor filtering of the first output signal. The second switched-capacitor stage outputs a second output signal that is sent to a low pass filter to form a continuous analog signal associated with the digital signal.
