Classification: CPC H | IPC H

Claim 10:
11. An electronic device, comprising:
a decoupling capacitor having a first terminal electrically connected to a diode and a second terminal configured to receive a first voltage, the decoupling capacitor comprising:
a first MOM capacitor comprising a first finger and a second finger arranged in parallel;
a MIM capacitor over the first MOM capacitor and comprising a conductive layer, wherein the first terminal is connected to the first finger of the first MOM capacitor, and the second terminal is connected to the second finger of the first MOM capacitor or the conductive layer of the MIM capacitor; and
a dielectric layer between the MIM capacitor and the first MOM capacitor;

wherein:
the diode includes at least one of a laser diode, a CMOS image sensor (CIS) pixel unit, an OLED pixel unit, or a combination thereof;
the first terminal of the decoupling capacitor is electrically connected to an anode of the diode; and
the first voltage is lower than a voltage at the first terminal.
