Abstract :
This paper describes a 15-bit CMOS cyclic A/D converter that incorporates an improved correlated double sampling technique to effectively boost the op-amp gain by the square of its design value. The increased op-amp gain reduces op-amp non-linearity as the signal swing is maximized for signal to noise ratio in a low voltage CMOS process.
