The key design target is to comply with EMI (electromagnetic interference) specification limits. The two main aspects are low EME (electromagnetic emission) and sufficient immunity against RF disturbance. A gate driver is proposed which uses a certain current summation network for lowering the slew rate on the one hand and being reliable against radio frequency (RF) disturbances within the automotive environment on the other hand. Nowadays the low cost single wire LIN Bus is used for establishing communication between sensors, actuators and other components.","PeriodicalId":236992,"journal":{"name":"2015 10th International Workshop on the Electromagnetic Compatibility of Integrated Circuits (EMC Compo)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132196773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 2-μm-thick crossed anisotropy multilayered Co-Zr-Nb film was applied onto the passivation layer of TEG chip. The in-band spurious was suppressed by 10 dB while it had no influence upon wanted signal. A magnetic near field map measured in the 2.1 GHz range indicated several noise coupling paths on chip, which were compared with the chip layout design to estimate victim wires. EM simulation model in connection with circuit simulation is carefully constructed. RF control wirings were most responsible wires than other wires and air couplings.

The literature has plenty of solutions aimed at keeping EMI filters' attenuation as high as possible in the widest possible frequency range. However such filters are less effective than expected because of the parasitic elements introduced by interconnects. As a consequence, EMI can be propagated into ICs causing temporary or definitive operation failures. This paper points out the causes of EMI-induced errors in high-side current sensors based on low-offset chopper OTAs. Analyses presented in the paper are supported by direct power injection measurements carried out on a test chip.","PeriodicalId":236992,"journal":{"name":"2015 10th International Workshop on the Electromagnetic Compatibility of Integrated Circuits (EMC Compo)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132285188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The chip is realized in 40 nm CMOS technology, the one used for the realization of automotive microcontroller. Four versions of the chip are presented and some measurements are shown. This first paper focuses on emissions aspects, even if the schematic architecture and layout has been developed to cover immunity phenomenon too. To understand the role played by the silicon substrate as propagation medium (noise internally generated to outside or to convey the external environment interferences into the silicon circuitries), the ESD pin protections have been removed on two versions of the test chip. The same electrical architecture is also proposed in different layout designs: with and without the Deep N-Well (DNW) implant allowing isolation of p-well substrates, to evaluate the benefit of this process technique. Previous work is discussed, and new hypotheses and emission measurements are shown. This work is focused on the basic version of the test chip, without DNW and ESD protection, to highlight noise propagation due to the substrate only, without intervention of different physical structures.","PeriodicalId":236992,"journal":{"name":"2015 10th International Workshop on the Electromagnetic Compatibility of Integrated Circuits (EMC Compo)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123065909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we proposed shielding structures for TSV to active circuit noise coupling in 3D IC. The proposed structures can capture TSV substrate noise by blocking the noise paths to active circuit, LC-VCO in this study. The noise suppression mechanisms are analyzed by the noise coupling coefficient in frequency-domain obtained by 3D electromagnetic simulation.

To evaluate the radiative immunity of an integrated circuit, we employ the IEC-standardized IC stripline method. In this paper, we provide an electromagnetic immunity analysis of the radiated electromagnetic noise coupling from an IC stripline to a ring voltage-controlled oscillator (VCO). We present the design of an IC stripline that meets the IEC 62132-8 standard, the test setup and the experimental results of the VCO test chip. The measurement shows that the radio frequency (RF) source from the IC stripline causes changes in the center frequency and output characteristics. VCO output variations show that the design is relatively immune to radiated noise of the same frequency as the oscillator output, and the output frequency spectrum spreads out more with higher noise amplitude due to injection. The experiment shows that the IC stripline method is an effective solution for the radiated electromagnetic analysis of an IC.","PeriodicalId":236992,"journal":{"name":"2015 10th International Workshop on the Electromagnetic Compatibility of Integrated Circuits (EMC Compo)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116317933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
