Abstract

The unique phenomenology of transducers complicates designing the interface of the transducer-to-pico-network protocol. This paper will explore the methodologies and issues involved in the design flow of a mixed-signal microchip through a sensor-to-pico-network design example that has been fabricated in the AMI 0.5 /spl mu/m process. The design methodologies include a careful decomposition between the digital and analog sections, as well as between the individual analog blocks, which decreases time-to-market and enhances design reuse. The fabricated design includes a 4-20 mA receiver, a second-order Sigma-Delta Modulator, fourth-order sinc filter, and an SPI block.
传感器到微网络应用的片上系统设计方法和问题
传感器独特的现象学使传感器到微网络协议的接口设计变得复杂。本文将通过在AMI 0.5 /spl μ m工艺中制造的传感器到微网络设计示例,探讨混合信号微芯片设计流程中涉及的方法和问题。设计方法包括数字和模拟部分之间以及各个模拟模块之间的仔细分解,从而缩短了上市时间并提高了设计的可重用性。该设计包括一个4- 20ma接收器、一个二阶Sigma-Delta调制器、一个四阶sinc滤波器和一个SPI模块。
