Data converter based on semiconductor devices

A data converter configured to convert an analog signal, which is an input signal, into a digital code composed of N bits, where N is a natural number, the data converter comprising:

• a reference signal input unit configured to provide a preset reference signal;
• and
• N bit processing units configured to respectively correspond one-to-one to the N bits constituting the digital code and receive the input signal and the reference signal to generate and output a code of a corresponding bit,
• wherein each of the bit processing units comprises:
• a signal generation module including a first semiconductor device having a first threshold voltage set according to a corresponding bit position within the digital code, the input signal being applied to the signal generation module;
• and
• a comparison module including a second semiconductor device having a second threshold voltage, the reference signal being applied to the comparison module;
• a latch module configured to regenerate a potential of an internal node according to operation results of the first semiconductor device and the second semiconductor device based on the input signal, the first threshold voltage, the reference signal and the second threshold voltage;
• and
• a signal conversion module having an input node connected to an output node of the latch module and configured to convert an output voltage of the latch module into a binary signal and output the binary signal.
