The use of a quadratic slope instead of a conventional linear slope makes a damping factor and a frequency bandwidth of a current feedback loop independent of the converter's output voltage. Further designing the coefficient of the quadratic slope to be fully dependent of the input voltage, the damping factor and the frequency bandwidth become completely independent of both the input and output voltages. A test chip of a buck converter in a 5 MHz operation which uses a quadratic slope compensation scheme has been fabricated by using a 0.35 mum CMOS process. The evaluation results show that with a current capability of up to 500 mA the frequency characteristics of the total loop are constant when the input and output voltages change from 3.3 V to 2.5 V and from 2.5 V down to 0.5 V, respectively, and also that the recovery time is 50 mus with a peak voltage deviation of less than 50 mV for load current changes from 20 mA to 200 mA and vice versa.","PeriodicalId":121828,"journal":{"name":"ESSCIRC 2007 - 33rd European Solid-State Circuits Conference","volume":"3 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":"114121255","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 data retention voltage (DRV) defines the minimum supply voltage for a cell to hold its state. Within-die variation causes a statistical distribution of DRV for individual cells in a memory array, and cells far out the tail (i.e. >6sigma) limit the array DRV for large memories. We present two statistical methods to estimate the tail of the DRV distribution. First, we develop a new statistical model based on the connection between DRV and static noise margin (SNM). Second, we apply our Statistical Blockade tool to obtain fast Monte-Carlo simulation and a generalized Pareto distribution (GPD) model for comparison. Both the new model and the GPD model offer a high accuracy (<2% error) and a huge speed-up (>104times for 1 G-b memory) over Monte-Carlo simulation. In addition, both models show a very close agreement with each other at the tail even beyond 7sigma.","PeriodicalId":121828,"journal":{"name":"ESSCIRC 2007 - 33rd European Solid-State Circuits Conference","volume":"12 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":"116189844","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}
