The modulation and control signal are applied to the oscillator transmission gates via the floating current source circuit. The current of this source repeats the input control current that includes two components, one of which tunes the mid-frequency and the other tunes the modulation depth. Each of the control components is set independently. This precise and wide-range frequency control allows one to use it in multiband applications. The proposed circuit is designed in 0.18 mum standard digital CMOS process for intended carrier frequencies of two ISM bands (900 MHz, and 2.4 GHz).","PeriodicalId":247684,"journal":{"name":"2008 1st Microsystems and Nanoelectronics Research Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126720524","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 identify several factors that can cause the performance of different BioFET cells in an array to differ, causing unwanted background variations between the cells of a microarray. These variations add up to the already existing noise sources, such as the electrolyte noise, the FET noise, and the reference electrode drift. We also introduce techniques that can potentially speed up the hybridization process, reduce the noise, and enhance the sensitivity.","PeriodicalId":247684,"journal":{"name":"2008 1st Microsystems and Nanoelectronics Research Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129084581","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 the proposed approach, the spectrum of an ultrashort optical pulse generated by a mode-locked fiber laser is spectrally shaped and at the same time wavelength-to-time mapped by the LCFBG to generate a microwave pulse with a shape identical to that of the shaped optical spectrum. By designing the LCFBG to have an arbitrary reflection profile, a microwave arbitrary waveform is generated. The key component in the proposed system is the LCFBG. A simple and effective technique to synthesize the LCFBG with an arbitrary reflection response is proposed. An approximate model describing the microwave AWG is derived, which is verified by numerical simulations and a proof-of-concept experiment.","PeriodicalId":247684,"journal":{"name":"2008 1st Microsystems and Nanoelectronics Research Conference","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126198857","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}

This effect is commonly observed when a significant amount of gold is used to design MEMS devices that are fabricated using PolyMUMPsreg. To study and overcome the galvanic effect on these devices, three methods are proposed: (1) connecting the device to a poly0 ring; (2) increasing the device surface area and (3) grounding the device to the substrate. The three methods are compared for their effectiveness in preventing galvanic corrosion. It is observed that although all three methods can considerably restrain the galvanic effect, grounding the device to the substrate is the best solution.","PeriodicalId":247684,"journal":{"name":"2008 1st Microsystems and Nanoelectronics Research Conference","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125479206","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}

One of the major challenges in building an integrated transceiver is minimizing the crosstalk between the high powered laser driver for the upstream signal, and the sensitive transimpedance amplifier for the downstream signal. The system described in this paper uses a novel modulation scheme called offset sideband modulation (OSBM) for the downstream signal such that the received electrical signal is an RF bandpass signal which does not interfere with the baseband signal that generates the upstream signal. The transceiver architecture is discussed, and simulation results are presented for a number of the system components.","PeriodicalId":247684,"journal":{"name":"2008 1st Microsystems and Nanoelectronics Research Conference","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127779357","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 force sensor consists of flexible structural members, to which two electrodes are attached, which deflect under the application of grasping forces, and a thermal actuator. A feedback controller is developed to maintain a constant tunneling current across the two electrodes, thereby maintaining constant displacement of the electrodes. Measurement of the voltage applied to the thermal actuator to maintain a constant electrode displacement allows the grasping force to be determined. The design and modeling of the force sensor are addressed. The fabrication of sharp tunnel tips using commercially available MEMS process is investigated. A sharp tunnel tip with width less than 100 nm is achieved using the PolyMUMPs process. The electron tunneling force sensor has extremely high sensitivity, which make it very suitable for micromanipulation tasks.","PeriodicalId":247684,"journal":{"name":"2008 1st Microsystems and Nanoelectronics Research Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122581382","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}
