Abstract: An analog to digital converter includes a digital to analog converting circuit, a comparator and a signal processing circuit. The digital to analog converting circuit samples and holds an analog input signal, and converts digital output data to an analog signal to generate a hold voltage signal. The comparator compares the hold voltage signal with a reference voltage signal in response to a rising edge and a falling edge of a clock signal to generate a comparison output voltage signal. The signal processing circuit performs successive approximation based on the comparison output voltage signal to generate the digital output data.
