A 3 V CMOS video acquisition channel

A complete video acquisition channel has been integrated in a 0.6 /spl mu/m double-poly CMOS process. The system includes a video clamp, AGC, S/H amplifier, and 10-bit ADC. The signal chain is fully differential, and achieves /spl plusmn/0.35 LSB DNL at 14.3 MS/s dissipating 90 mW from a 3 V supply. The active area is 2.85 sq mm.
