Abstract

Future wireless transceivers must support several communication standards with low-cost, low-area and low power consumption. In this letter, a novel wide tunable CMOS active inductor dedicated to RF circuits for multistandard applications is presented. Only negative transconductors are considered in the proposed gyrator instead of the conventional one. To save the silicon area, the new active inductor is implemented employing puch-pull amplifier cells as negative transconductors. Using a $0.13-\mu m$ CMOS technology, the obtained simulation results (a) show a wide frequency range inductive behavior with high self resonance frequency. High quality factors are reached with good agility while covering the frequency range of 2 to 2.6 GHz and consuming a dc power of 0.9 to 1.3mW from 1 V of supply voltage.

Abstract

This paper presents a sub-1mW radiofrequency voltage controlled oscillator (VCO) design optimization approach. The relation between components and specifications of the LC-VCO is studied, which allows to easily identify its design trade-offs. This approach has been applied to optimize the design of two different topologies of sub-1mW LC-VCOs in 130nm CMOS process suitable for IoT applications. The first VCO is using the current-reused technique and the second one is based on CMOS cross-coupled topology operating in the sub-threshold region. Post-layout simulation results in both circuits show a total power consumption of only $136\mu \mathrm {W}$ and $267\mu \mathrm {W}$ with a phase noise of-114dBc/Hz @lMHz at the operation frequency of 2.4GHz.

Abstract

International audience; Perception is one of the most important tasks for safe navigation of autonomous mobile robots in outdoor environments that are dynamic and unknown. This paper presents a real time system for detection and classification of dynamic objects using a 2D laser range finder (2D LRF) and a moving camera mounted on the mobile robot. An occupancy grid based detection is implemented using 2D LRF and moving objects are iteratively extracted from the global occupancy grid. A visual classification system is developed using HOG features and AdaBoost as learning process. Dynamic objects detection and visual classification results are coupled to point moving camera on the specified target (specified by mission supervisor) and to identify it. Finally, real time experiments results on the mobile robot in two different scenarios are presented.
