Abstract :
A 1.2V 6b 1GS/s ADC is fabricated in a 90nm CMOS process, occupies 0.13mm2, and consumes 55mW. This ADC uses background offset-calibration to enable the use of minimum-size devices in pre-amplifiers and comparators. A solution that guarantees fast selection of the important reference voltages, and halves the number of switches in the resistor ladder, further improves high-frequency performance
