Unconsidered but influencing interference in unmanned aerial vehicle cabling ...IJECEIAES
The increasing complexity of electrical and electronic systems in unmanned aerial vehicles (UAVs) has raised concerns regarding unwanted electromagnetic interference (EMI) due to limited compartment space. Recent studies have highlighted the UAV cabling as the primary pathway for interference. This paper presents a novel approach to investigating the effects of interference power, polarization angle, and distance from the interference source on EMI in UAV cable systems. Measurements and simulations were performed to analyze the influence of these factors on the radiation received by the cable. A linear dipole antenna, operating at a frequency of 905 MHz, served as the radiation source, while a single wire cable pair terminated with a 50-ohm resistor was employed as the victim. The findings reveal that the power transmitted by the source, the distance between the cable and the source, and the polarization angle have a significant impact on the electromagnetic interference received by the cable. Notably, a perpendicular orientation of the cable to the interference source (antenna) in the far-field yielded a reduction of up to 15 dBm in EMI. The results underscore the necessity for more sophisticated models and comprehensive measurements to fully comprehend the diverse factors affecting polarization losses in practical scenarios.
A 2.98 dB NF, 2.52 mW Ultra-Wideband Low Noise Amplifier for a Brain Neuromod...SAKIB REZA
This work presents a low noise amplifier (LNA) for
lower ultrawideband (UWB) applications. The proposed LNA is
based on a current-reuse common source (CS) architecture so as
to achieve energy efficiency without sacrificing the noise
performance. With 1.2V supply voltage, the proposed LNA
consumes 2.52 mW power and achieves a 16.81 dB peak gain at 4.2
GHz frequency, with a 3-dB bandwidth of 1.28 GHz. The average
noise figure (NF) achieved is 2.98 dB over the 3-dB bandwidth. The
design is realized using a standard 0.18 µm CMOS process. The
characteristic of the proposed amplifier makes it a proper
candidate to be applied for implantable medical devices.
The Federal Communications Commission (FCC)
designated the 3.1-10.6 GHz frequency band for unlicensed
ultra-wideband (UWB) use back in 2002 promoting
commercial mass-market practices. UWB technology has
sparked substantial interest in both educational and commercial
enterprise because of its promise to provide high-speed shortrange wireless data transmission with considerable energy
efficiency.
UWB technology has shown promise for a number of
applications including Wireless Personal Area Networks
(WPAN) [1][2] and Wireless Sensor Networks [3]. UWB
communication uses the 3.1-10.6 GHz frequency spectrum
(lower band: 3.1-5 GHz; higher band: 6-10.6 GHz). The
development of the first generation UWB system will take
place in the low frequency range (3.1-5 GHz). When
considering time to market, hardware cost, degree of
complexity, and other factors, CMOS technology is a good
choice for implementing a low band UWB system [4]
Multiple channels are used to capture and transmit data in
high data rate biomedical applications such as neural signal
recording systems for brain-computer interface. The neural
recording system proposed in [9] uses a 128-channel system to
transfer the recorded brain signal at a data rate of 90 Mbps while
consuming only 6 mW of power. As the number of channels or
sample rate of the Analog to Digital Converter (ADC) increases,
so does the data rate. As such, the power consumption also
increases. As a result, it is critical to decrease power
consumption for such high data rate applications.
The novelty of this work is to design an energy-efficient
front-end amplifier exploiting 180 nm CMOS process which
enables the receiver chain to be operated in the UWB frequency
spectrum making it suitable for high data rate biomedical
applications. The design architecture of the proposed LNA is
discussed in section II. In section III, the simulation results are
provided followed by a concluding remark in section IV
The circuit diagram of the proposed LNA is shown in Fig.
1. It consists of four stages including input matching stage,
common source first stage, current reuse stage and the output
matching stage. The input matching network consists of the
capacitors C1 and C2 and the inductor L1 and L2. L2 is in series
resonance with the total capacitance connected to the gate
terminal of transistor MN1
