The design and test of peripheral circuits of image sensor for a digital camera

The invention of the digital camera creates not only a new technology for photography, but also new applications and developments with the combination of electrical devices. Compared to traditional cameras, the digital camera has the following advantages: image could be stored easily, image could be repaired, image could be deleted, and image could be transmitted through network. This paper presents first the basic and how to acquire image of the CMOS sensor, and then design the peripheral circuits of CMOS sensor and power management for a digital camera. Finally, to verify the digital camera does it meet the EMC (ESD, EFT/B and EMI) international verification standard.
