Abstract

Visible Light Positioning (VLP) provides a promising means to achieve indoor localization with sub-meter accuracy. We observe that the Visible Light Communication (VLC) methods in existing VLP systems rely on intensity-based modulation, and thus they require a high pulse rate to prevent flickering. However, the high pulse rate adds an unnecessary and heavy burden for receiving with cameras. To eliminate this burden, we propose the polarization-based modulation, which is flicker-free, to enable a low pulse rate VLC. In this way, we make VLP light-weight enough even for devices with a camera. This paper presents the VLP system PIXEL, which realizes our idea. In PIXEL, we developed 1) a novel color-based modulation scheme to handle user's mobility and 2) a sensor-assisted positioning algorithm to ease user's burden in capturing multiple location anchors. Our experiments based on the prototype show that PIXEL can provide $10$ cm-level real-time VLP for wearables and smartphones with camera resolution as coarse as 60 pixel × 80 pixel and CPU frequency as low as 300 MHz.

Abstract

In this brief, a low-voltage low-temperature- coefficient (TC) subthreshold CMOS voltage reference (CVR) is presented. The proposed CVR employs the ${\Delta }\text{V}_{\mathbf{GS}}$ of different-threshold and same-threshold nMOS transistor pairs to generate the complementary-to-absolute-temperature and proportional-to-absolute-temperature voltages, respectively. Low TC with small variations and high power supply ripple rejection (PSRR) are achieved. The proposed design is fabricated in a standard 0.18- $ {\mu }\text{m}$ CMOS process. It measures an average reference voltage of 218.3 mV with a deviation of 0.97 mV and variation coefficient of 0.45%. It achieves an average TC of 23.5 ppm/°C for a temperature range of −40 °C to 125 °C. The measured PSRR is −66.4 dB, −42.4 dB and −42.3 dB at 10 Hz, 1 kHz and 10 MHz, respectively. The measured line sensitivity is 0.40%/V for 0.6 V to 2.0 V supply. The consumed power is 30.5 nW at 0.6-V supply. [ABSTRACT FROM AUTHOR]
