Abstract
An image sensor having a pixel part generating a signal in accordance with a light, a signal processing part performing signal processing on the signal read from the pixel part, and a power supply part connected to the signal processing part via a first wiring, and supplying a power supply to the signal processing part, and a storage package storing the image sensor, and having a second wiring configuring a parallel circuit by being connected to the first wiring. Accordingly, it is possible to solve a problem such that a wiring resistance is increased when a power supply circuit is configured inside of a solid state image sensor.
Claims18
A signal processing apparatus comprising:
- a first signal line to which is output a first signal generated from photoelectric-converted electric charge;
- a second signal line to which is output a second signal generated from photoelectric-converted electric charge;
- a first signal processing part performing signal processing on the first signal output to the first signal line;
- and
- a second signal processing part performing signal processing on the second signal output to the second signal line;
- and
- a first wiring to provide a power supply voltage from a power supply circuit to the first signal processing part and the second signal processing part, wherein
- the first wiring is connected in parallel with a second wiring provided on outside, and a length from the power supply circuit to the first signal processing part is different from a length from the power supply circuit to the second signal processing part.
An electronic device comprising:
