CMOS technology is also used for analog circuits such as image sensors (CMOS sensors), data converters, RF circuits , and highly integrated transceivers for many types of communication. The CMOS process was demonstrated by Fairchild Semiconductor's Chih-Tang Sah and Frank Wanlass at the International Solid-State Circuits Conference in 1963
By 2012, CMOS sensors increased their share to 74% of the market. As of 2017, CMOS sensors account for 89% of global image sensor sales. [27] In recent years, [when?] the CMOS sensor technology has spread to medium-format photography with Phase One being the first to launch a medium format digital back with a Sony-built CMOS sensor.

The two main types of digital image sensors are the charge-coupled device (CCD) and the active-pixel sensor (CMOS sensor), fabricated in complementary MOS (CMOS) or N-type MOS (NMOS or Live MOS) technologies.

Exmor R is a back-illuminated version of Sony's CMOS image sensor. [5] Exmor R was announced by Sony on 11 June 2008 and was the world's first mass-produced implementation of the back-illuminated sensor technology. [6] [non-primary source needed] Sony claims that Exmor R is approximately twice as sensitive as a normal front illuminated sensor.
A further development is the stacked CMOS sensor, [3] which layers the circuitry and image signal processor (ISP) behind the pixels, allowing the active pixel to occupy even more area, further increasing the chance of light capture. Sony, which announced the first stacked sensor in January 2012, claims a 30% increase in light captured. [20]
This is a list of smartphones with a primary camera that uses a 1.0-type (“1-inch”) image sensor or larger. However, as of February 2024, there are no smartphones that use a sensor larger than 1.0-type. The first camera phone to feature a 1.0-type sensor was the Panasonic Lumix CM1 in 2014. Seven years passed before another phone featured ...
A CMOS sensor with PPD technology was first fabricated in 1995 by a joint JPL and Kodak team that included Fossum along with P.P.K. Lee, R.C. Gee, R.M. Guidash and T.H. Lee. Further refinements to the CMOS sensor with PPD technology between 1997 and 2003 led to CMOS sensors achieve imaging performance on par with CCD sensors, and later ...
