Provided is a chip including a plurality of unit cells; a scanning circuit adapted to scan the plurality of unit cells, thereby making each of the plurality of unit cells output a signal; a voltage-to-current conversion circuit; a current-to-voltage conversion circuit; an output terminal; and an input terminal. The current-to-voltage conversion circuit is adapted to convert a first current signal input into the input terminal, into a first voltage signal, the scanning circuit starts scanning in response to the first voltage signal output from the current-to-voltage conversion circuit, and the voltage-to-current conversion circuit is adapted to convert a second voltage signal output from the scanning circuit into a second current signal, and to output the second current signal from the output terminal. |
