This paper proposes a model for a miniaturized signal conditioning system for biopotential and ion-selective electrode arrays. The system consists of three main components: sensors, interconnections, and signal conditioning chip. The model for this system is based on SPICE. Transmission-line based equivalent circuits are used to represent the sensors, lumped resistance-capacitance circuits describe the interconnections, and a model for the signal conditioning chip is extracted from its layout. A system for measurements of biopotentials and ionic activities can be miniaturized and optimized for cardiovascular applications based on the development of an integrated SPICE system model of its electrochemical, interconnection, and electronic components. 相似文献

柔性电子技术在近些年得到了快速发展,越来越多的柔性电子系统需要柔性、高性能的集成电路来实现数据处理和通信。通过减薄硅基芯片可以获得高性能的柔性集成电路,但是硅基芯片减薄之后的性能有可能发生变化,并且在制备、转移、封装的过程中极易产生缺陷或者破碎,导致芯片性能退化甚至失效。因此,超薄硅基芯片的制备工艺和柔性封装技术对于制备高可靠性的柔性硅基芯片十分关键。在此背景下,文章综述了柔性硅基芯片的力学和电学特性研究进展,介绍了几种超薄硅基芯片的减薄工艺和柔性封装前沿技术,并对超薄硅基芯片在柔性电子领域的应用和发展进行了总结和展望,为柔性硅基芯片技术的进一步研究提供参考。 相似文献

Alongside innovative device, circuit, and microarchitecture level techniques to alleviate power and thermal problems in nanoscale CMOS-based integrated circuits (ICs), chip cooling could be an effective knob for power and thermal management. This paper analyzes IC cooling while focusing on the practical temperature range of operation. Comprehensive analyses of chip cooling for various nanometer scale bulk-CMOS and silicon-on-insulator (SOI) technologies are presented. Unlike all previous works, this analysis employs a holistic approach (combines device, circuit and system level considerations) and also takes various electrothermal couplings between power dissipation, operating frequency and die temperature into account. While chip cooling always gives performance gain at the device and circuit level, it is shown that system level power defines a temperature limit beyond which cooling gives diminishing returns and an associated cost that may be prohibitive. A scaling analysis of this temperature limit is also presented. Furthermore, it is shown that on-chip thermal gradients cannot be mitigated by global chip cooling and that localized cooling can be more effective in removing hot-spots. 相似文献

This paper highlights the development and effectiveness of a multichip module (MCM) Design-For-Testability methodology for an application intended for use in a fully electronic active matrix LCD flight instrument. MCM test issues discussed include Design-For-Testability, substratetest, Known-Good Die (KGD) and module level test.The design incorporates IEEE 1149.1 and Built-In-Self-Test features. Bare die pretest is accomplished with a Ball Grid Array (BGA) chip carrierapproach.The hardware consists of a mature digital design comprised of application specific and industry standard integrated circuits. 相似文献

Today mainly submicron CMOS and BiCMOS technologies are used for the design of mixed analogue-digital applicationspecific integrated circuits (ASIC). This allows to integrate complete systems. Overall system costs are reduced and the reliability of the complete system can be improved. Today’s electronic systems often contain sensors to convert non-electric signals followed by electronic amplifiers, filters, analogue-to-digital converters and digital signal processing. The advantages of analogue and digital signal processing can be integrated on a single IC and for some applications it is even possible to include the sensor on the silicon chip. 相似文献
