Abstract
An ADC includes an analog signal input port for receiving analog signals, a reference voltage generation circuit for producing a reference voltage, a controllable switch, a control unit including a counter, an integral circuit, and a comparison circuit. The control unit outputs an on or off signal to turn on or turn off the controllable switch, the counter starts to count when the control unit outputs the off signal. The integral circuit executes an integral action to integrate the reference voltage and output a voltage enhanced gradually when the controllable switch is turned off. The comparison circuit outputs an interrupt signal to cause the counter to stop counting when comparing the voltage output by the integral circuit is higher than the voltage of the analog signals. The control unit determines a digital value corresponding to the analog signals according to a count value of counted by the counter.
