Abstract
Provided is an algorithm analog-to-digital converter (ADC). The algorithm ADC obtains two digital outputs through different capacitor connections for one analog input signal and adds the digital output signals to obtain a final output value, so that a mismatch factor of the capacitor is removed to minimize a linearity limitation resulting from the capacitor mismatch. In addition, the algorithm ADC minimizes power consumption by making the operating frequency slow at a cycle requiring a high resolution and making the operating frequency fast at a cycle requiring a low resolution, i.e., outputting different operating clock frequencies according to a required resolution.
