The transmitter is designed for high data rate wireless communication. It employs up conversion concept. The up conversion concept is to multiply Gaussian monocycle pulse with 6.4 GHz sine wave to push the spectrum of Gaussian monocycle pulse into higher frequency band. As a result, the FCC spectral mask can be used efficiently. The transmitter presented contains 6.4 GHz VCO source, divide-by-32 high frequency prescaler, Gaussian monocycle pulse generator, Gilbert cell BPSK modulator, differential to single converter, RF mixer and driven amplifier. The circuits are designed in 0.18 um RFCMOS technology from IMF (Institute of Microelectronics). Simulation showed the correct operation of the circuit for supply voltages of 1.8 V and a power consumption of 195 mW. And the transmitted pulse covers frequency bandwidth from 3.1 GHz to 10.6 GHz. All the circuit simulations are done by HPADS.","PeriodicalId":337918,"journal":{"name":"2005 IEEE International Wkshp on Radio-Frequency Integration Technology: Integrated Circuits for Wideband Comm & Wireless Sensor Networks","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134603921","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}

SC sigma-delta modulator can provide robust performance, but at low center frequencies. Its CT counterpart is able to operate at much high frequency, but its performance is often impaired by low-Q CT loop filters and the need of frequency tuning. In this paper, an alternative approach is introduced. Bandpass sigma-delta modulators employing electromechanical resonators as loop filter are described. As a proof-of-concept, a second- and fourth-order bandpass sigma-delta modulator are demonstrated in a 0.35-/spl mu/m CMOS process using off-chip SAW resonators with a resonant frequency of 47.3 MHz. The dynamic ranges, measured in a 200-kHz signal bandwidth when sampled at 189.2 MHz, are 57 dB and 69 dB for the second- and fourth-order modulator, respectively. The chips operate under a 3.3-V single supply with a power dissipation of 30 and 45 mW, respectively.","PeriodicalId":337918,"journal":{"name":"2005 IEEE International Wkshp on Radio-Frequency Integration Technology: Integrated Circuits for Wideband Comm & Wireless Sensor Networks","volume":"36 16","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134259899","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}
