Abstract :
This paper describes a low-power BiCMOS A/D converter using a "differential voltage subconverter", which directly converts a voltage difference of complementary analog inputs to a digital code. This conversion technique reduces power consumption and signal delay in the A/D converter. Several circuit techniques have also been newly developed to achieve high-accuracy conversion with single 5 V power supply. The 10-bit A/D converter is fabricated in a 0.8 /spl mu/m BiCMOS process and it operates at 50 MS/s with 500 mW.
