PREDICTIVE SUCCESSIVE APPROXIMATION REGISTER ANALOG-TO-DIGITAL CONVERSION DEVICE AND METHOD |
摘要 |
A predictive successive approximation register analog-to-digital conversion device and method are provided. A difference between two input signals of a comparator is detected according to a threshold less than or equal to 1/2 of a voltage increment represented by one least significant bit (LSB). When a difference between a first analog signal and a second analog signal is less than a threshold, a detection circuit enables a bit in a digital signal corresponding to a comparison cycle to which the difference belongs to be forcedly decided to be a first value and predicts values of the remaining bits. |
