e2v on CCD vs CMOS Sensors
AZO Materials publishes Teledyne e2v article "The Development of CMOS Image Sensors" with a table comparing CCD and CMOS sensors. Although I do not agree with some of the statements in the table, here it is:Characteristic | CCD | CMOS |
---|---|---|
Signal from pixel | Electron packet | Voltage |
Signal from chip | Analog Voltage | Bits (digital) |
Readout noise | low | Lower at equivalent frame rate |
Fill factor | High | Moderate or low |
Photo-Response | Moderate to high | Moderate to high |
Sensitivity | High | Higher |
Dynamic Range | High | Moderate to high |
Uniformity | High | Slightly Lower |
Power consumption | Moderate to high | Low to moderate |
Shuttering | Fast, efficient | Fast, efficient |
Speed | Moderate to High | Higher |
Windowing | Limited | Multiple |
Anti-blooming | High to none | High, always |
Image Artefact | Smearing, charge transfer inefficiency | FPN, Motion (ERS), PLS |
Biasing and Clocking | Multiple, higher voltage | Single, low-voltage |
System Complexity | High | Low |
Sensor Complexity | Low | High |
Relative R&D cost | Lower | Lower or Higher depending on series |
