A 1.5 V 8b 8 mW BiCMOS video A/D converter

Abstract

Video ADCs embedded in mixed-signal system LSIs for battery-operated, hand-held multimedia terminals must operate at 0.9-1.5 V supply to reduce system power. By combining the high transconductance and good matching of bipolar transistors with the circuit flexibility of MOS switched capacitor (SC) circuits, a 1.5 V BiCMOS video ADC shows analog BiCMOS has potentially higher performance than CMOS even at 1.5 V.
