Abstract: Disclosed is an analog-to-digital conversion device. The analog-to-digital conversion device includes a signal generating unit that generates a plurality of comparison voltages based on an analog input voltage and generates a plurality of comparison results of the plurality of comparison voltages based on a sampling period, a calculation unit that skips a comparison result generated by a comparison voltage having a smallest difference between the analog input voltages among the plurality of comparison voltages from the plurality of comparison results and generates an end of comparison based on a remaining plurality of comparison results, and a SAR logic unit that generates a digital signal corresponding to the end of comparison and stores information for each bit of the digital signal.

Abstract: Provided is an electronic device for factorization of a target number. The electronic device includes an energy calculating circuit configured to generate input values for updating bits of a candidate number based on an energy function that has a minimum when the candidate number is a factor of the target number, and bit updating circuits corresponding to the bits of the candidate number, respectively.
