An asynchronous 6bit 1GS/s ADC is achieved by time interleaving two ADCs based on binary successive approximation algorithm (SA) using a capacitive ladder. The semi-close loop asynchronous technique eliminates the high internal clocks and significantly speeds up the SA algorithm. One bit redundancy is implemented to compensate the process variation of parasitic and the MOM capacitance. Fabricated in 65nm CMOS with an active area of 0.11mm2, it achieves a peak SNDR of 31.5dB at 1 GS/s sampling… CONTINUE READING
