小面积、微功耗增量型Sigma-Delta ADC设计
Compact, Micro-power Incremental Sigma-Delta ADC Design
摘要
Abstract
The analog-to-digital converter (ADC) plays an important role in array sensor applications. This kind of applications imposes very stringent power and chip area restriction to the ADC. On the other hand, the sensor itself requires high-resolution of the ADC. All these requirements place challenge to the ADC design. By carefully study of the ADC topology, the incremental Sigma-Delta ADC is proposed as it produces better resolution, power and chip area trade-off. The topology and the circuit design of the proposed incremental Sigma-Delta ADC are introduced in details. Implemented in a 0.18mm CMOS technology, the proposed ADC consumes 58mW power consumption at the conversion speed of 40kS/s and produces 15bit digital output. The chip area of one single ADC is 10mm×530mm. The measurement result proves the proposed incremental Sigma-Delta ADC is suitable for array sensor applications.关键词
