A/D converter, image sensor, and digital camera

An A/D converter includes: an A/D converter circuit that causes a dissipation current (Idis) having dependence on an input voltage (Vin); and a counteracting current generation circuit controlled based on an output digital value (Dout) provided from the A/D converter circuit to generate a counteract...

Zusammenfassung:An A/D converter includes: an A/D converter circuit that causes a dissipation current (Idis) having dependence on an input voltage (Vin); and a counteracting current generation circuit controlled based on an output digital value (Dout) provided from the A/D converter circuit to generate a counteracting current (Icnt) that is a dissipation current for reducing the dependence of the dissipation current (Idis) on the input voltage.
