We explore the vectorial optomechanical interaction between a nanowire and a focused beam of light. The nanowire is sensitive to the topological variations of the focused laser force field which dramatically modify the phenomenology of the dynamical backaction. The non-conservative topology of the optomechanical interaction is responsible for a novel canonical signature of strong coupling between...
We report ultra-low threshold optically induced self-oscillations of a ultra-low dissipation nanowire. We interpret the asymmetrically observed responses as a signature of the laser shot noise drive, consistent with our system's parameters.

We present the design of an ultra low power sixth-order Butterworth low pass GmC filter in 0.13 ??m CMOS process. A method to optimize the power consumption of a fully differential telescopic OTA is also presented to achieve an input linearity of 220 mVpp and transconductance value of 6 ??S. The OTA is then used to implement an ultra low power filter and to show the impact of parasitic capacitances...
This paper discusses the design of a 60 GHz low noise amplifier (LNA) using a standard low power SOI CMOS process from ST Microelectronics. First, we outline the technology as well as the mm-wave design challenges. Using recent work on coplanar waveguide (CPW) modeling, we describe how it's possible to use parametric, 3D electromagnetic simulation to complete or replace analytical models of on-chip...
