Abstract :
An area-efficient 10-bit 6.5 Msps digital to analog converter (DAC), for the transmit and power ramping DACs of a GSM mixed signal solution, is presented. Using a segmented mismatch shaping approach, the design simultaneously offers the signal to noise ratio needed to achieve good modulation accuracy, and the low out-of-band noise needed to satisfy transmit emissions requirements specified in the GSM standard.
