| Abstract(in English) | Video/still signal processing such as white balancing is usually performed in digital domain. However, in the case of color image sensors, becase of the sensitivity deviation among R, G and B pixels, the SNR is limited by the low sensitivity pixel. This problem can be solved by processing the white balancing in analog domain. This paper proposes a new programmable gain amplifier (PGA) with white balancing. The proposed GCA with analog white balancing allows us to achieve higher SNR in the amplified image while maintaining sufficient gain precision of 10bit and low power dissipation. A prototype PGA is implemented using 0.6 um CMOS technology. The power dissipation is 120mW at supply voltage of 3.3V and 20MHz pixel rate. |
