The SoC includes 900MHz RF transceiver, PA, MODEM, MCU, memory and peripherals with fully compliant ISO/IEC 18000–6C and EPC Global Class1 Gen2 reader protocol. The receiver 1% PER sensitivity is −88dBm at RF input port. The class-A PA is integrated in the transmitter, with 20dBm CW carrier output power. The fully integrated fractional-N frequency synthesizer with a 3.6GHz LC VCO is implemented for low wide band phase noise. The LO phase noise is −104.7dBc/Hz at 100KHz offset frequency and −130.6dBc/Hz at 1MHz offset frequency. The SoC satisfies a multiple-interrogator environment's ACPR requirement of the ISO/IEC 18000–6C standard. In operating Tag read mode, the SoC dissipates 980mW when transmitting a 20dBm CW carrier signal. The die area of the SoC is 17.1mm2, of which 7.6mm2 is used by the 900MHz RF transceiver and PA.","PeriodicalId":239979,"journal":{"name":"2011 Proceedings of the ESSCIRC (ESSCIRC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130407423","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}

Moreover, it is found that the oscillator is robust to the tank mistuning. The proposed oscillator achieves a phase noise of −102 dBc/Hz at 1 MHz offset from 57.6 GHz, consuming 7.2 mW from a power supply of 0.6 V.

These products emanate from a combination of a low-order nonlinearity and the narrowband nature of the signal of interest. In this work, a scrambling system is proposed that can be added to a receiver, reducing these distortion products. Continuous time-domain signal manipulation is used to spread the spectral power of a narrowband signal, before it passes through nonlinear receiver circuitry. Digitally the original signal shape is reconstructed. This way, the distortion created by the nonlinearity does not result in dominant tones, improving IP2 and IP3 figures without increasing the intrinsic circuitry linearity, saving power and maintaining flexibility. This topology became possible through using new designs and topologies, which allow signal manipulation using passive components only. Additionally, a new high speed DAC design allows a voltage supply rail to be used as a sub-mV accurate reference. The concept is demonstrated using a software-radio approach, in which the sampling and buffering represents the nonlinear processing. With a 2.2Vpp, diff 100 MHz input signal, the measured distortion products are below −74 dBc. At 1.4 GHz input this number is 60.2 dBc. The scrambling hardware uses 54 mW in a 65nm CMOS process.","PeriodicalId":239979,"journal":{"name":"2011 Proceedings of the ESSCIRC (ESSCIRC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130185511","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}
