- Abstract
High speed digital to analog converter (DAC) are always used in signal processing system to accomplish the signal reconstruction, where the spurious free dynamic range (SFDR) of the system is especially important. The SFDR determines the ability of DAC and the system to distinguish the carrier signal from other spurs. By increasing the output impedance of the high speed DAC will help to lower the nonlinearity, thus improve the SFDR. This paper describes the technique which will reduce the nonlinearity by increasing the output impedance of the DAC, which can achieve 14 bit resolution and 1.2GSPS, and SFDR 76dBc@FDAC=1.2GHz, FOUT=50MHz.
