An 8-bit subranging AD converter was fabricated by 65-nm CMOS technology featuring an ultra-low-power AD converter architecture without resistor ladder, a low-power offset adjust circuit and an offset drift compensation technique. As a result of evaluating the test chip, it was turned out that the transmission characteristics deviated from the designed value at both ends of the input range. The failure analysis clarified that the mismatch of the MOM capacitor in the capacitive DAC degraded the transmission characteristics. Moreover, SNDR of 41.8 dB and FOM of 61 fJ/conv.-step were obtained when the input signal was limited to the center region of the input range. It was also confirmed that the error due to the offset drift can be reduced to 0.3 LSB even when the temperature changed by 60°C. |
