Unlike conventional position sensitive detectors (PSDs), it is capable of simultaneous multiple spot detection with high accuracy. To decrease signal processing overhead characteristic of this kind of area arrays, binary detection with on-site thresholding and random access readout is used. The fill factor and pitch of the array are 30% and 50 /spl mu/m, respectively. Quantization limited position sensing accuracy of 4.3 /spl mu/m is achieved using spot of a 280 /spl mu/m in diameter, total signal power of about 8 nW and pulse width of 8 ms. The sensitivity is limited by the spatial noise caused by the mismatch of threshold setting current mirrors operating in weak inversion.","PeriodicalId":111737,"journal":{"name":"Proceedings of CICC 97 - Custom Integrated Circuits Conference","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127719844","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 reduced junction capacitance and near-ideal MOS device characteristics of SOI provides an inherent advantage for low-voltage low-power applications. Substantial progress in applying SOI technology for these applications has been demonstrated in recent years. The quest for a single chip system has also initiated work in developing high frequency and analog SOI circuits. In this paper, the application of Thin-Film-Silicon-On-Insulator (TFSOI) technology for wireless communication systems is reviewed and future development discussed.","PeriodicalId":111737,"journal":{"name":"Proceedings of CICC 97 - Custom Integrated Circuits Conference","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127933883","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 consequence is the down scaling of the power supply voltages, to date even lower than 2 V, with almost the same threshold voltages of the CMOS transistors. Those low voltages mean that some widespread techniques such as switched-capacitors cannot be implemented anymore. On the other hand custom integrated circuits require continually higher speeds, more accuracy and less power drain. In the first section, the impact of mismatch or accuracy in analog circuits and the impact on power drain is discussed. Secondly, in section two some fundamental limitations of analog integrated circuit design in the trade-off between speed, accuracy and power drain are analysed. In the third section the problem of very low voltage signal processing in switched-capacitor circuits is studied. Some solutions, such as the switched-opamp technique are presented, and the technique is demonstrated by the design of a very low power, low voltage sigma delta modulator. The design and the measurements of 12 bit sigma delta AD converters running at 1.5 V power supply voltage and consuming less than 100 /spl mu/W in standard CMOS technology are finally discussed.","PeriodicalId":111737,"journal":{"name":"Proceedings of CICC 97 - Custom Integrated Circuits Conference","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122670062","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 circuit is based on a poly-phase implementation of a traditional all-digital architecture. A digital-to-analog current-division wave-shaping converter serves as an FIR bandwidth limiting filter. Digital data is applied at the input and an analog waveform is produced at the output, without the need for a standard D/A converter at the back-end, thus reducing power consumption and area. The circuit has been fabricated in a 0.8 um CMOS process (MOSIS HPCMOS26G), occupies an area of 1.2-mm/spl times/1.213-mm, and dissipates 20-mW from a single 5 V supply. The maximum baud rate of the modulator is 10-Mbaud. The 33-tap FIR wave-shaping filter insures out-of-band ripples are suppressed by more than 30-dB. This modulator is applicable to broadband digital communication such as wireless telephony, wireless modems and digital video.","PeriodicalId":111737,"journal":{"name":"Proceedings of CICC 97 - Custom Integrated Circuits Conference","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131303826","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}
