Abstract: | In this paper, a 12‐bit multi‐channel dual‐mode successive approximation ADC for PMBus devices is newly proposed. The proposed data converter is attractive because all the requirements of PMBus devices, which are high resolution, low‐cost, dual‐mode, and multi‐channel, are successfully matched. In measurement results, all the functions and performance of the proposed data converter are successfully verified and confirmed to be applied on PMBus devices. The area of this chip is 1.64 × 1.56 mm2, and the measured power consumption including digital output buffers is 1.683 mW. The proposed 12‐bit multi‐channel dual‐mode successive approximation ADC is suitable for power monitoring systems, such as PMBus devices. Copyright © 2011 John Wiley & Sons, Ltd. |
