Abstract :
This paper describes an I/Q channel 12bit 120MS/s digital-to-analog converter (DAC) for WLAN application. The proposed DAC implemented in 0.35mum CMOS n-well process employs three stage 4 bit thermometer decoders to minimize glitch energy and linearity error. The measurement results show a plusmn1.6LSB/plusmn1.3LSB of INL/DNL and 31 pVmiddots of glitch energy. ENOB and SFDR are measured to be 10.5bit and 71.09dB @ Fs = 120MHz and Fin = 1MHz with a total power consumption of 105mW
