“…Ultrawide band (UWB) is a wireless carrier communication technology that does not use a sinusoidal carrier but uses narrow pulses of nonsinusoidal waves at the nanosecond level to transmit data, thus covering a wide spectrum. UWB technology has the advantages of low system complexity, low power spectral density of transmitted signals, insensitivity to channel fading, low ability of interception, and high positioning accuracy, which is especially suitable for high-speed wireless access in dense multipath places such as indoor [13].…”

In order to overcome the problems of the traditional algorithm, such as the time-consuming execution of acquisition instructions, low signal tracking accuracy, and low signal capture accuracy, a global satellite positioning receiver acquisition and tracking algorithm based on UWB technology is designed in this study. On the basis of expounding the pulse generation method and working principle in UWB technology, this paper analyzes in detail the characteristics of UWB technology, such as antimultipath, low power consumption, and strong penetration. Then, on the basis of window function filtering, in the process of three-dimensional search of global satellite positioning signal, firstly, the satellite signal entering the GPS software receiver is processed by RF front-end mixing and AD sampling, and then, the signal tracking and navigation message solving are completed according to the relationship between the influence factor and Doppler frequency offset. The experimental results show that the execution time of the acquisition instruction of the proposed algorithm varies between 1129 ms and 1617 ms; the signal tracking accuracy ranges between 0.931 and 0.951, and the signal capture accuracy ranges between 93.3% and 95.6%, which proves that the proposed algorithm has achieved the design expectation.

“…As mentioned, UWB receivers need high linearity to suppress the cross-modulation/inter-modulation due to the increased co-existence of adjacent blockers. Many techniques have been published to enhance the LNA's linearity in recent year such as multiple gated transistor technique (MGTR) [25], post-distortion technique [26], derivative superposition (DS) technique [27], and complementary derivative superposition (CDS) [28]. One of the conventional methods of removing harmonic distortion (HD) and improving linearity is DS technique in which two parallel transistors are called main and auxiliary.…”

This paper presents a new ultra-wide band (UWB) CMOS low noise amplifier (LNA) with very high linearity and low power consumption for UWB wireless communication applications, where linearity is a big challenge, due to presence of interference and blocker signals, as well as the in-band harmonics of the desired signal components in the lower part of UWB band. The proposed LNA uses a new combination of saturated NMOS and PMOS transistors to improve both of second order and third order nonlinearities, meanwhile improving the noise performance and DC power consumption. In our design two techniques are integrated in a novel approach: Improved Complementary Derivative Superposition (ICDS) technique and Forward Body Bias (FBB) to reduce the threshold voltage of MOSFET, and hence, lowering the DC power. By utilizing a high-pass filter and common source stage in cascode form, wideband impedance matching and optimal noise figure (NF) have been obtained in the proposed UWB-LNA. The Post-layout simulation of the linearized LNA in a 180 nm RF CMOS process shows NF between 2.5 and 4 dB, gain of 10.8 ± 0.5 dB, and S 11 less than -10 dB in the entire 3.1-10.6 GHz band. Total DC power consumption is only 6 mW with 1.2 V supply voltage. The average and the maximum of IIP3 in the UWB band are ? 3.84 dBm and ? 7.27 dBm, respectively, a superior linearity performance compared to the reported UWB ones. The chip area is 926 mm 9 1075 mm, including the supply and ESD ring and the pads.

“…The most important characteristics of the LNAs include low noise, high linearity, and highpower gain. Ultra-wideband (UWB) applications are needed in electronic consumers, such as vehicular radars with high-accuracy operations (Rafati, Qasemi and Amiri, 2019;Kumaravel, et al, 2016;Zhang and Sánchez-Sinencio, 2010;Wang, 2021;Roobert and Rani, 2020). Ultra-wideband systems are approved for use in 3.1-10.6 GHz bandwidth.…”

Ultra-wideband (UWB) applications require low-power and low-noise amplifiers (LNAs) that can operate over a wide frequency range. However, conventional LNAs often suffer from poor linearity and high-power consumption. This research work proposes a novel LNA design that uses the adjusted derivative superposition (DS) technique and feedback to improve the linearity and reduce the power consumption of UWB LNAs. The DS technique enhances the third-order intermodulation (IM3) cancellation by adjusting the bias currents of the transistors, whereas the feedback improves the stability and input matching of the LNA. The LNA is implemented using a degenerated common source topology in a 180 nm standard CMOS technology. The simulation results show that the LNA achieves a power gain of 10–12.2 dB, an input third-order intercept point (IIP3) of about 12 dBm, and a noise figure of less than 2.5 dB over the UWB frequency band of 3.1–10.6 GHz. The input reflection coefficient is less than -10 dB, and the power consumption is 11.6 mW with a 1.5 V power supply. The designed LNA offers a novel and innovative solution for UWB applications that significantly improve the performance and efficiency of UWB LNAs whereas reducing the cost and complexity of implementation.
