Abstract :
This paper reports a successive-approximation analog-to-digital converter (ADC) which combines the bypass window and direct switching technique to tolerate the incomplete settling error and reduce the control logic delay. A small unit capacitor cell reduces the power consumption and settling time. The 10-bit prototype is fabricated in a 40nm CMOS process. At 200 MS/s and 0.9-V supply, this ADC consumes 0.82 mW and achieves an SNDR of 57.16 dB, resulting in an FOM of 13.9 fJ/Conversion-step.
