Hardware and software equipment for the complex investigation of the wireless smart transducers used in the systems for controlling thermodynamic parameters of energy carries was developed on the basis of National Instruments equipment. Stand tests and qualify transducers by the parameters of radio channel and power supply simulating real conditions of exploitation. Software on the development environment...
Ambient RF energy harvesting becomes one of the potential renewable energies for powering low power electronic devices such as autonomous sensors in wireless sensor networks (WSN). Comparing to other ambient energy sources, RF energy has the lowest density power, although it can be harvested all day and night. Our current research aims to build an RF energy harvesting system prototype using ultra...
This paper presents an energy-efficient, customizable, high-data-rate, impulse radio ultra wideband (IR-UWB) transceiver, operating in three channels within 3–5GHz for centimeter-to-meter range biotelemetry. Fabricated in 90nm 1P/9M CMOS, the transceiver integrates an all-digital transmitter (TX) with a waveform-synthesis pulse generator and a timing generator for pulse modulation and phase scrambling,...
Having been demonstrated at frequencies up to 6.2 GHz with measured Q's >; 4,000, micromechanical resonators hold great promise for enabling on-chip high-Q passives needed in wireless communication systems. However, the acceptance of such devices in present-day transceivers has been hindered by their excessive motional impedances and feedthrough parasitics that prevent direct integration with...
A low-voltage (0.5 V) and low-power (4.535 mW) monolithic biomedical system-on-a-chip (SOC) consisting of a receiver, a transmitter, a microcontrol unit, and an analog-to-digital converter (ADC), implemented in a 0.18-μm CMOS technology for intrabody communication is first reported. The SOC can take command through a human body and activate (or turn on) the ADC and transmitter inside the SOC. Then,...
