Based on the circuit architecture, both classifications and comparisons are made. Then we propose a high speed phase frequency detector for PLL design. The proposed phase frequency detector is simple in its structure and has no glitch output as well as better phase characteristics. Furthermore, some simulations results by HSPICE are performed based on 0.35 mum process parameters. Several prior art phase frequency detectors with the proposed one are compared for phase sensitivity, dead zone characteristics and maximum operation frequency. Based on simulation results, the proposed phase frequency detector shows satisfactory circuit performance with higher operation frequency, lower phase jitter and smaller circuit complexity. The speed of the proposed phase frequency detector is up to 3.5GHz. Moreover, the circuit design of a GHz PLL has been completed including high speed VCO, charge pump and phase frequency detector with an external loop filter. The total layout size excluding pads is 216.3mum times 47.85mum. The post-layout simulations for 1.1 GHz PLL loop operation has been shown and verified","PeriodicalId":231135,"journal":{"name":"48th Midwest Symposium on Circuits and Systems, 2005.","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131150161","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 outcomes of various information exploitation experiments are vital in protecting both manned and unmanned airborne platforms. The development of jamming waveforms and ECM techniques are based upon the exploitation data and circuit analysis of various threat hardware and firmware. Unfortunately these current manual methods are very time consuming and nontrivial. Vast resources are allocated just to the setup and investigation/evaluation of a particular system's circuit design. Several very complex information technology exploitation tests must also be executed for the purpose of deriving basis waveforms from the resultant empirical data. Since the results are empirical and not optimized, additional problems may arise at a later date. Consequently, the use of genetic algorithms (GAs) executing inside special signal-processing platforms that are integrated into existing ECM/ECCM testing systems may offer an innovative computational approach/solution in the development of optimized jamming information technology waveforms and techniques. If successful, the time required for developing these techniques could possibly be reduced from years to days if not hours.","PeriodicalId":231135,"journal":{"name":"48th Midwest Symposium on Circuits and Systems, 2005.","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131016072","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}

Also, the output current preserves a wide region of work up to five decades of current range. Post-layout simulations realized in HSPICE are presented.
