A K-band 65 nm CMOS low dc power low phase noise phase-locked loop (PLL) using divide-by-three injection-locked frequency divider (ILFD) is presented in this paper. Based on the injection-locked technique for the first stage of the frequency divider chain, the proposed PLL can be operated up to K-band with low dc power consumption. The ILFD features high division, high speed, and low power. With a...
An intensity modulation-based curved waveguide sensor is developed in this paper for vibration measurements. Measurement of vibration is an important aspect in aerospace and automotive structures. The sensor is created using a single-mode optical fiber, where coupling between the fundamental and cladding modes at certain curvatures results in intensity peaks that enables the development of a high-sensitivity...
Electromagnetic interference emissions radiated from electronic products above 1 GHz are more concerned by people especially for those from Information Technology Equipment at present time. To serve the EMC testing for product manufacturer, a commerical testing laboratory is sometimes asked and confused by the customer on the differences between CISPR and FCC rules for their products. We make some...
