ABSTRACT:
A circuit device according to the present invention comprises a plurality of transistor pairs, the number of which corresponds to a quantizing bit number, each of the plurality of transistor pairs being a pair of transistors having respective control electrodes connected to each other and respective first primary electrodes connected to each other, and a connecting line arranged to connect in series a second primary electrode of one transistor of one transistor pair among the plurality of transistor pairs to first primary electrodes of another transistor pair among the plurality of transistor pairs so as to constitute a binary-weighted current source. With the above-described arrangement, it is possible to reduce an area to be occupied by the circuit device and it is also possible to miniaturize the circuit device. Further, it is possible to reduce the cost of the circuit device.
