Abstract: PURPOSE: A resolution improving device and a method thereof using an analog to digital converter port inside a MCU are provided to improve the resolution of an analog signals inputted from outside. CONSTITUTION: A resolution improving device of an analog to digital converter (ADC) comprises a bisectional unit (110), an adding device (120), and a MCU (130). The bisectional part divides an analog input signal into 2 halves for outputting the signal of a sub part. The adding device adds the analog input signal to the signal of the sub part which is outputted from the bisectional part for outputting. The MCU receives the analog input signal through a first ADC port and receives the main part signal of the signal divided into 2 halves through a second ADC port or an input and output port. The MCU converts the main part signal into a digital signal when a signal is inputted through the input and output port and assigns 1 to an additional bit above the most significant bit for outputting. The MCU converts the analog signal into the digital signal when a signal is not inputted through the input and output port and assigns 0 to the additional bit above the most significant bit for outputting.
