For the integrator, a cross-coupled transistor pair is used as a negative resistance generator. A novel ultra-fast reset circuit is implemented which allows to reset the integrator within very short time of 120 ps. The chip was fabricated using 130 nm SiGe BiCMOS technology with fT of 250 GHz and fmax of 300 GHz. In the measurements carried out on printed circuit board, the correlator operated without noticeable performance degradation with inputs up to 33 Gbps which correspond to a bandwidth of more than 24 GHz. The correlator exhibits high linearity with output P1dB of more than 9.9 dBm (700 mVdiff) for both inputs. It dissipates 122.5 mW for the core circuit excluding the 50 Ω output driver. To the knowledge of the authors, the circuit represents the fastest analog correlator published so far. It can be used for spread spectrum communication, radar signal processing, and measurement applications.","PeriodicalId":431327,"journal":{"name":"2016 IEEE Bipolar/BiCMOS Circuits and Technology Meeting (BCTM)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114602412","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 transceivers include a frequency multiplier that generates the 61 and 122 GHz carrier signals from a single external 30.5 GHz LO signal that is also fed to an output buffer in the transceivers. The proposed architecture enables the cascading of multiple transceivers and allows thus the implementation of a MIMO radar system with 2 different frequency bands.

This novel bipolar transistor consists of a shallow emitter confined by shallow trench isolation (STI), a base with multiple regions each serving a different purpose without compromising one another, and a lightly doped collector region surrounded by continuous p-type regions biased with the base potential. The base region below the emitter has a relatively low dopant concentration and is crucial to the carrier transport; the relatively more heavily-doped and deep base region between the emitter and collector effectively confines the depletion of the collector; and the p-type region above the collector as well as the p-epi surrounding the collector enable the collector to be fully depleted when the collector is biased high. Attributed to these unique features, the npn bipolar transistor exhibits superior characteristics, including a high current gain of 83, a high Early voltage of 1750V, and a high BVceo of 59V.","PeriodicalId":431327,"journal":{"name":"2016 IEEE Bipolar/BiCMOS Circuits and Technology Meeting (BCTM)","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124725129","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}
