发明名称 Digital-to-analog converter with improved output impedance switch
摘要 A digital-to-analog converter includes a number of current steering cells. In each current steering cell, a current source is biased by a differential amplifier to provide a high output impedance. The high output impedance in the current steering cell allows the digital-to-analog converter to operate under low supply voltage conditions.
