IP개요 | In this work, a two-step SAR ADC is proposed applicable to high-speed CIS systems. The design techniques are as follows. Firstly, to reduce the area, we use resistor DAC (RDAC) and capacitor DAC (CDAC) separately, and the resistor DAC applies a certain layout technique, called cross-connected layout method, to increase device matching. Secondly, to resolve settling time issue by using resistor, bit-cycling time control logic and LSB correction logic have been implemented for enhancing sampling speed of the ADC. |
