A 14b Low-power Pipeline A/D Converter Using a Pre-charging Technique

A pre-charging technique to improve the settling response of pipeline stages is demonstrated in a Mbit pipeline A/D converter (ADC). The prototype ADC fabricated in a 0.25μm CMOS process consumes 102mW at 30 MSample/s. Measured SNDR and SFDR are 70.7dB and 82.8dB, respectively.
