Abstract
A successive approximation analog to digital converter and a conversion method thereof are provided. The successive approximation analog to digital converter includes a sample circuit, a conversion circuit, and a filtering control circuit. The sample circuit is configured to sample an analog voltage from an analog signal. The conversion circuit is configured to convert the analog voltage into a digital voltage. The filtering control circuit is configured to transmit a filtering control signal to the sample circuit according to the digital voltage. The sample circuit further samples a next analog voltage from the analog signal and adjusts the next analog voltage into an adjusted analog voltage according to the filtering control signal. The conversion circuit further converts the adjusted analog voltage into a next digital voltage, wherein the next digital voltage is a filtered digital voltage.
