Abstract :
A workload-balanced multiplying digital-to-analog converter (WB-MDAC) is proposed to improve the settling efficiency of multi-bit pipeline stages, and demonstrated in a 14-bit 50-MS/s digital calibrated pipelined ADC. The presented ADC occupies an active area of 1.3 mm2 in 0.13-μm 1P8M CMOS technology, including internal reference buffers. It dissipates 76mW from a 1.2-V supply, and achieves 64.4 dB SNDR and over 80 dB SFDR.
