    Two radio frequency integrated circuit (RFIC) downconverters are presented, each consisting of an active mixer and a variable gain amplifier (VGA). The downconverter blocks (DCBs) have identical mixing stages but different VGA topologies. The mixers use a commutating switching network and a low-noise RF transconductance stage to reduce the system noise figure (NF). VGA gain control in one DCB (DCB... View full abstract»

    To address the growing demand for high-quality multimedia applications on mobile devices, stronger smartphones based on multicore processors are becoming the mainstream. However, processing power is still behind the required resources for some multimedia applications such as new video coding standards. Mobile cloud computing is a solution for this concern. In order to efficiently distribute tasks ... View full abstract»

  • RFFE: A Buffer Cache Management Algorithm for Flash-Memory-Based SSD to Improve Write Performance

    Publication Year: 2015, Page(s):219 - 231

    Flash-memory-based solid-state drives use multiple NAND flash memory chips as storage media and deploy a large-sized random access memory (RAM) inside it. This RAM buffer absorbs the read and write requests by file systems, and thus the resulting write requests to NAND flash memory are determined by the buffer replacement scheme. Many of the previously proposed algorithms concentrate on improving ... View full abstract»

  • Designing Linear PAs at Millimeter-Wave Frequencies Using Volterra Series Analysis

    Publication Year: 2015, Page(s):232 - 237

    Power amplifiers (PAs) at millimeter-wave (mm-wave) frequencies are required for delivering high output linear power while being efficient; however, their performance is severely affected by the scaled semiconductor technology and the operating frequency. To improve the linearity of mm-wave PAs, it is recommended that an external linearization technique such as predistortion be used. The PA presen... View full abstract»

    The growing demand for plug-in electric vehicles (PEVs) in the world has driven researchers to pay extra attention to charging stations (CSs) in order to meet supplying needs. Lower emission, convenient charging experience, high performance, and energy security are considered as the significant benefits of the mentioned technology. Despite the aforementioned advantages, inappropriate place and siz... View full abstract»

    It has been a challenge to determine the optimal energy-storage capacitance in piezoelectric vibration energy harvesting (VEH) systems for a given working time. In this paper, the PSPICE software is used to determine the optimal energy-storage capacitance in a VEH system with one or more piezoelectric modules, for maximizing the energy harvesting capability, and to investigate the dependence of th...

    In this paper, we present the design of an observer-based controller for perturbed mechanical systems using two-independent adaptive sliding-mode structures (ASMSs). The purpose of the proposed method is to compensate for external disturbances and modeling uncertainties of general mechanical plants. Assuming that only position measurements are available, the proposed control approach is based on a... View full abstract»

    Nowadays, advanced forgery and spoofing techniques are threatening the reliability of conventional biometric modalities. This has been motivating the recent investigation of a novel yet promising modality transient evoked otoacoustic emission (TEOAE), which is an acoustic response generated from cochlea after a click stimulus. Unlike conventional modalities that are easily accessible or captured, ... View full abstract»

    In this paper, we present an approach to jointly minimize energy consumption of wireless transmitters and harmful interference on sensitive medical devices, and optimize the central controller placement for collecting data from transmitters. In particular, a multiobjective nonconvex mixed-integer nonlinear programming problem is formulated to optimize transmit power of wireless users and central p... View full abstract»
