This manuscript details our latest 90nm CMOS W-band receiver design where the RF LNA, resistive mixer, IF differential amplifier and LO tripler have been integrated, thus allows the whole 77–110GHz spectrum to be down-converted into quasi-DC −33GHz using a much lower microwave frequency. In addition to being used in our broadband receiver array project, this W-band circuit is also eligible for the...
This manuscript describes our W-band LNA design using commercial 90nm CMOS process. For effectively extending the amplifier's bandwidth without compromising its wideband matching or noise figure, a combination of common-source and cascode gain stages are employed for the five-stage circuit design. This 1200×900μm2 low-noise amplifier has more than 10dB gain and around 12dB noise figure, with 41mW...
We report on the design of a temperature-compensated power amplifier module which can generate 20Watt output power with 34dB gain at 14GHz. This module is made of one commercial microwave monolithic integrated circuit and three discrete power transistors. Allowing gate biases of these power transistors to be automatically adjusted with ambient temperature, output power of the module can now be more...
We compared the clinical efficacy and safety between a new injectable cyclooxygenase-2 selective inhibitor, parecoxib, and an old nonselective, ketorolac combined with morphine in patient-controlled analgesia (PCA) for management of post-cesarean delivery pain.In this randomized, open-label study, 66 parturients undergoing cesarean section were divided into two groups: In Group P the patients received...
The support vector machine (SVM) classifier is a popular and appealing classifier .It could be improved by taking some transformation about the original data before classification even sometimes its performance is not good,. In our previous paper, two transformations, NWFE-Transformation and Liu-Transformation are considered. The results showed that the SVM with our Liu-Transformation algorithm has...
In search of good classifier of hosts of influenza A viruses is an important issue to prevent pandemic flu. The hemagglutinin protein in the virus genome is the major molecule that determining the range of hosts. In this paper, a novel classification algorithm of hemagglutinin proteins integrating SVM and logistic regression based on 4 kinds of Hurst exponents for each protein sequence is proposed...
