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
