15 GHz quadrature voltage controlled oscillator in 130 nm CMOS technology

This paper reports a 15 GHz quadrature voltage controlled oscillator (QVCO) designed in a 130 nm CMOS technology. The phase noise performance of the QVCO and of a phase locked loop (PLL) where the QVCO was inserted were compared with the literature and with telecom standards and commercial products for broadcast satellite applications

TREX reveals proteins that bind to specific RNA regions in living cells.

Different regions of RNA molecules can often engage in specific interactions with distinct RNA-binding proteins (RBPs), giving rise to diverse modalities of RNA regulation and function. However, there are currently no methods for unbiased identification of RBPs that interact with specific RNA regions in living cells and under endogenous settings. Here we introduce TREX (targeted RNase H-mediated extraction of crosslinked RBPs)-a highly sensitive approach for identifying proteins that directly bind to specific RNA regions in living cells. We demonstrate that TREX outperforms existing methods in identifying known interactors of U1 snRNA, and reveals endogenous region-specific interactors of NORAD long noncoding RNA. Using TREX, we generated a comprehensive region-by-region interactome for 45S rRNA, uncovering both established and previously unknown interactions that regulate ribosome biogenesis. With its applicability to different cell types, TREX is an RNA-centric tool for unbiased positional mapping of endogenous RNA-protein interactions in living cells

A 130nm CMOS Tunable Digital Frequency Divider for Dual-Band Microwave Radiometer

An inductorless, divide-by-256 fixed-modulus digital frequency divider with programmable input sensitivity, fabricated in 130 nm CMOS bulk process, is presented. Both the absence of inductors and the architecture used allow to obtain a small sized chip. The fabricated frequency divider exhibits two minima in sensitivity at 4.4 GHz and 6.25 GHz consuming about 5.4 mW from a 1.2 V voltage supply. The total active area of the frequency divider is 360umx 115um
