Abstract :
A highly integrated 30 MSample/s video analog front end for >2M pixels camera with 36 dB of programmable pixel-by-pixel gain achieves 73 dB SNR. Dynamic bias in a 12b pipeline ADC results in 48 mW power with 0.4 LSB DNL. The die is 7.6 mm/sup 2/ in 0.35 /spl mu/m CMOS with 110 mW power at 2.7 V.
