An intrinsic stress source - shallow trench isolation - has not been fully utilized up to now for circuit performance improvement. In this paper, we present a new methodology that enables the exploitation of STI stress for performance improvement of standard cells and custom integrated circuits. We start with process simulation of a 65 nm STI technology, and generate mobility models for STI stress based on these simulations. Based on these models, we are able to perform STI stress-aware modeling and simulation using SPICE. We then present our optimization of STI stress in standard-cell and custom designs using active-layer (dummy) fill insertion to alter the STI widths. Circuit level experimental results are based on a miscellaneous ring oscillator, which is known to correlate well to silicon. Using a generic 65 nm cell library, we show that the STI-optimized designs provide up to 8% improvement in clock frequency. The frequency improvement through exploitation of STI stress comes at practically zero cost with respect to area and wire length.","PeriodicalId":130106,"journal":{"name":"2007 IEEE Custom Integrated Circuits Conference","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132372456","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}

Most receivers offer DC offset cancellation circuitry, and a targeted non-zero DC offset at mixer output is up-converted to RF carrier frequency due to poor reverse isolation of the mixer switch. By controlling amplitude of the injected DC, IIP2 degradation due to LO leakage at the input of RF amplifiers can be compensated. Mathematical analysis and measurement data for a quad-band GSM/GPRS receiver implemented in 90-nm digital CMOS process are presented. Calibrated IIP2 of 50 dBm is reported at LNA input.","PeriodicalId":130106,"journal":{"name":"2007 IEEE Custom Integrated Circuits Conference","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134321680","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 addition, the method of two-path is applied to reduce the capacitance value such that the total integration can be achieved. The proposed SSCG has been fabricated in a 0.18 mum CMOS process. The clock of 1.5 GHz with down spread ratio of 0.5% is realized for applications to serial ATA. The 19.63dB EMI reduction (RBW=10 KHz) and 35 ps-pp period jitter are achieved in this study.

The common Simulink design description minimizes errors in translation of the design between different descriptions, and eases the verification burden.
