Abstract :
This paper presents an integrated 4-bit MDAC for highspeed high-resolution pipelined ADCs which employs a code-by-code analogue self-calibration technique. Measured results from the prototypes fabricated in a 1.0 μm CMOS technology show that the proposed self-calibration technique corrects the MDAC linearity and the interstage gain to the 14-bit level, while allowing conversion rates in the MHz range
