Image sensors and optical devices

Compared with CCD image sensors, which is a general advantage of CMOS image sensors?

  1. APixel charges are transferred in sequence and read out at a single output
  2. BPeripheral circuits are easy to integrate on the same chip, and power consumption is low
  3. CThey cannot be manufactured with CMOS processes
Show answer and explanation

Answer: B. Peripheral circuits are easy to integrate on the same chip, and power consumption is low

A CMOS image sensor has amplifying transistors in each pixel and can be made with standard CMOS processes, so peripheral circuits such as AD converters are easily integrated on the same chip and power consumption can be kept low. Transferring charge in sequence and reading it out at one place is how CCDs work.
