Abstract :
A 10-bit digital-to-analog converter (DAC) is presented that delivers 6-Vpp into a 100-Ω differential load. The circuit is implemented in 45-nm CMOS SOI, which provides benefits for using a FET-stack current buffer. The measured DNL is better than 0.44 LSB. The DAC consumes 476 mW and achieves a peak SFDR of 54.4 dB and a minimum IM3 of -55.6 dBc. This DAC demonstrates the largest output swing and highest power efficiency for a highresolution (>8b), high-speed (>100MS/s) DAC.
