An electronic device includes a voltage divider producing different reference voltages. Dummy pixels each are formed by a transfer gate transistor having a first conduction terminal coupled to a floating diffusion node, a second conduction terminal, and a control node coupled to a first gate signal line, a transmission gate coupled between one of the plurality of taps and the second conduction terminal of the transfer gate transistor, a floating diffusion capacitor coupled between the floating diffusion node and ground, a transistor having a first conduction terminal coupled to the floating diffusion node, a second conduction terminal, and a control terminal coupled to a second gate signal line, and a reset transistor having a first conduction terminal coupled to the upper reference voltage, a second conduction terminal coupled to the second conduction terminal of the transistor, and a control terminal coupled to a reset signal line.
