THREE NEW SPECIES FROM JIANGXI, CHINA, ARE DESCRIBED AND ILLUSTRATED: Stenuswugongshanus sp. n., Stenusmingyueshanus sp. n., and Stenussongxiaobini sp. n. A previously published key to the Chinese species of the Stenuscirrus group is modified to accommodate the new species.
In this paper, a Q-band CMOS low noise amplifier (LNA) exploiting transformer positive-negative feedback and noise cancelling is presented. The proposed low noise amplifier consists of a positive transformer feedback to achieve noise-reduction and a negative transformer feedback to obtain high reverse isolation and stability. The noise cancellation… (More)
