  • Method and apparatus for increasing a dynamic range of a digital to analog converter
    Patent number: 6747585
    Abstract: A digital to analog converter with increased dynamic range and improved linearity and method therefore includes an input (109) coupled to a digital word; a circuit, such as a typical digital to analog converter (103, 603), operable to convert the digital word to an analog signal (411, 611), such as an analog current (413, 613), that is proportional to the digital word in a discrete continuous fashion; and an output (106, 606) to couple the analog signal to a load (115), wherein the load is coupled to a bias voltage (407, 607) that increases the dynamic range or decrease the distortion of the analog signal.
