A 12-bit 75-MS

Precision amplifiers dominate the power dissipation in most high-speed pipelined analog-to-digital converters (ADCs). We propose a digital background calibration technique as an enabling element to replace precision amplifiers by simple power-efficient open-loop stages. In the multibit first stage o...
