摘要
A low-power, fast-settling reference buffer used for high-speed high-resolution ADC is proposed. A replica buffer forms a closed loop to stabilise the operating point and a cascaded gm-boosting technique provides sufficient low output impedance, all of which ensure a high performance for the proposed buffer. The measured results show that the proportion of power consumption by the proposed buffer over ADC is only 2.7%, while settling to 12-bit accuracy within 0.13ns.
