Patent ID: 8717219

Claim:
A semiconductor integrated circuit configured to convert a difference between a first analog voltage and a second analog voltage into a digital signal, the semiconductor integrated circuit comprising: m (m is an integer greater than or equal to 2) first capacitors, each of which comprises a first electrode and a second electrode, the first electrodes being connected to each other; m second capacitors, each of which comprises a third electrode and a fourth electrode, the third electrodes being connected to each other; a comparator configured to compare a voltage of the first electrode and a voltage of the third electrode; and a logic circuit configured to generate the digital signal based on a comparison result of the comparator, wherein the first analog voltage is inputted into the first electrode, the second analog voltage is inputted into the third electrode, and one of a ground voltage and substantially ½ of a voltage of an input voltage range of the semiconductor integrated circuit is inputted into each second electrode and each fourth electrode.
