Extended information: Application of CMOS in the field of digital cameras
CMOS is the abbreviation of Complementary Metal Oxide Semiconductor. It refers to a technology used to manufacture large-scale integrated circuit chips or chips manufactured using this technology. It is a readable and writable RAM chip on the computer motherboard. Because of its readable and writable characteristics, it is used on the computer motherboard to save the data after the BIOS sets the computer hardware parameters. This chip is only used to store data.
CMOS manufacturing technology is also used to make photosensitive elements of digital imaging equipment (common ones are TTL and CMOS), especially SLR digital cameras with larger formats. Although its use is very different from that of CMOS circuits in the past, which were mainly used as firmware or computing tools, it basically still uses CMOS technology. It only converts the function of pure logical operations into receiving external light and converting it into electrical energy, and then through The on-chip analog-to-digital converter (ADC) converts the acquired image signal into a digital signal output.
Compared with other logic series, CMOS logic circuits have the following advantages:
1. The allowed power supply voltage range is wide, which facilitates the design of power supply circuits
2. Logic swing Large, making the circuit strong in anti-interference ability
3. Low static power consumption
4. The isolation gate structure makes the input resistance of the CMOS device extremely large, thereby improving the ability to drive similar logic gates during CMOS Much better than other series
