Abstract
A digital to analog converter with output impedance compensation has an encoding unit, a current cell array, a summing unit and a compensation unit.The compensation unit is connected to output terminals of the DAC and provides a nonlinear impedance to compensate an original output impedance of the DAC. With the compensated output impedance, the SFDR performance and the linearity of the DAC are improved to obtain a superior input-to-output transfer curve.
