To increase the power gain by mitigating the effect of the base-collector capacitance, the first design uses a differential cascode topology with a 2.7 V supply voltage. The second design instead uses capacitive cross-coupling of a differential common emitter stage, previously not demonstrated in mm-wave SiGe PAs, and has a supply voltage of only 1.5 V. Low supply voltage is advantageous since a common supply can then be shared between the transceiver and the PA. To maximize the power gain and robustness, both designs use a transformer based interstage matching. The cascode design achieves a measured power gain, S21, of 16 dB at 92 GHz with 17 GHz 3-dB bandwidth, and a simulated saturated output power, Psat, of 17 dBm with a 16% peak PAE. The cross-coupled design achieves a measured S21 of 10 dB at 93 GHz with 16 GHz 3-dB bandwidth, and a simulated Psat, of 15 dBm with 16% peak PAE. Comparing the measured and simulated results for the two amplifier architectures, the cascode topology is more robust, while the cross-coupled topology would benefit from a programmable cross-coupling capacitance.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":"99 1","pages":"666-669"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78607781","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 focus will be mainly on challenges related to transistor level design using a standard 28 nm technology, nevertheless a system level overview will be also given. The proposed transmitter features feed-forward equalization with 8 taps (1 pre-cursor and 6 post-cursors, plus the main tap), whose strength is programmable with 16 discretization steps, optimizing the transmitter adaptability with reduced area. The proposed architecture is also able to tune its output impedance independently from the choice of the weights of the equalization tap. It features a 300 mV peak-to-peak eye diagram with 16 equalization levels and achieves a remarkably low 2.25 pJ/bit total power consumption (0.633 pJ/bit for the predriver+driver).","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":"1 1","pages":"321-324"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79132582","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}

In the proposed reference circuit, the PTAT voltage is generated by feeding the leakage current of a zero-Vgs NMOS transistor to two diode-connected NMOS transistors, both of which are in subthreshold region; while the CTAT voltage is created by using the body-diodes of another NMOS transistor. Consequently, low-voltage, low-power operation can be achieved without requiring resistors or BJTs, hence with small chip area consumption. The proposed circuit is designed in a 0.18-μm process. Simulation results show that it is capable of providing an 808mV reference voltage with 10ppm/°C from −30°C–125°C even with only 900mV supply voltage.
