Abstract :
A low-cost 1.5 V A/D converter has been realized in standard CMOS technology. It is based on a novel low-voltage switched-capacitor technique with a differential signal path. The conversion is programmable and insensitive to the capacitor ratio and the amplifier offset voltage. A complete n-bit conversion needs 3n clock cycles. The chip area is 6.8 mm2 in a 1.5 ¿m CMOS technology with threshold voltages of 0.8V.
