A 10-bit pipeline ADC using 40-dB opamps and calibrated customized references

Chen, Cheng and Yuan, Jiren LU (2007) 7th International Conference on ASIC p.249-252
Abstract
A 10-bit pipeline A/D converter using low gain (<= 40 dB) operational amplifiers (opamps) is presented. Without. interfering the normal analog-to-digital conversion, a continuous reference refreshing technique is exploited. This technique effectively reduces the gain requirement of opamp while the conversion speed is not compromised, allowing the use of simple cascode CMOS inverters. The compensation of finite gain of the opamp is made by using customized reference voltages that is calibrated periodically. The technique has been confirmed by intensive simulations. As a result of the relaxed opamp gain requirement, significant reduction in power consumption can be achieved.
