    摘要: A two-stage digital-to-analog converter for outputting an analog voltage in response to a M-bit digital input code includes a two-bit serial charge redistribution digital-to-analog converter having a high reference voltage input node for receiving a high reference voltage and a low reference voltage input node for receiving a low reference voltage, and a voltage selector. The voltage selector sets the high reference voltage and low reference voltage to selected levels depending on at least a portion of the M-bit digital input code.
