This paper presents a 1-THz radiating array using IHP 130-nm SiGe process. It is based on a highly-scalable 2D structure that uses a square grid of slots to simultaneously (1) maximize and synchronize the fundamental oscillation (ƒ0=250 GHz) and 4th-harmonic generation (4ƒ0=1 THz) of a large array of transistors, (2) synthesize standing-wave patterns with near-field cancellation at ƒ0, 2ƒ0 and 3ƒ0...
In this paper, a general approach to predicting the conducted emissions of switched-mode power converters is presented. The approach is based on a SPICE time-domain simulation. In order to generate the models used in the simulation and postprocessing, CAD printed circuit board layout data, datasheet information of discrete elements, measurement data of discrete elements and measurement data of the...
In this paper, we propose a method to optimize the product performance instantly by utilizing the internal voltage trimming circuit for Dynamic Random Access Memory (DRAM) memory. Specifically, we first define the verification wafer as the internal voltage characteristics using the clustering technique. Second, the optimized voltage conditions are applied to a normal wafer being matched with a verification...
As the density of NAND flash memory grows, the cell-to-cell interference caused by capacitive coupling among neighboring cells becomes a critical source of bit errors. Thus, it is important to precisely measure the value of capacitances to remove the interferences and lower the bit-error rate. Previous approaches have employed the least mean square (LMS) or the least square adaptive filtering approaches...
With the fast development of modern power semiconductors in the last years, the development of current measurement technologies has to adapt to this evolution. The challenge for the power electronic engineer is to provide a current sensor with a high bandwidth and a high immunity against external interferences. Rogowski current transducers are popular for monitoring transient currents in power electronic...
