Abstract:
In this paper we present the design of a fully integrated low noise amplifier for WiMAX standard with AMS 0.35 μm CMOS process. This LNA is designed to cover the frequency range for licensed and unlicensed bands of the WiMAX 2.3–5.9 GHz. The proposed amplifier achieves a wide band input and output matching with S11 and S22 lower than -10 dB, a flat gain of 12 dB and a noise figure around 3.5 dB for the entire band and from the upper to the higher frequencies. The presented wide band LNA employs a Chebyshev filter for input matching and an inductive shunt feedback for output matching with a bia

Abstract:
In this paper, a wide-band noise-canceling (NC) current conveyor (CC)-based CMOS low-noise amplifier (LNA) is presented. The circuit employs a CC-based approach to obtain wide-band input matching without the need for bulky inductances, allowing broadband performance with a very small area used. The NC technique is applied by subtracting the input transistor’s noise contribution to the output and achieves a noise figure (NF) reduction from 4.8 dB to 3.2 dB. The NC LNA is implemented in a UMC 65-nm CMOS process and occupies an area of only 160 × 80 μm2. It achieves a stable frequency response fr

Abstract:
In this paper, an ultra-wide band (UWB) low noise amplifier (LNA) is implemented by using 90nm RF CMOS technology. The designed LNA achieves high flat band gain (S21) and low noise figure (NF) in the frequency of interest. The proposed LNA operates in the frequency range of 3GHz to 8GHz. In this work, wide band matching is achieved by designing common gate configuration at the input stage. The current reuse and noise cancellation techniques are introduced to improve flat band gain and minimize both noise figure and power consumption. The noise figure is improved by cancelling dominant noise so

Abstract:
This paper proposes a microwave rectifier designed for the popular 5G band, featuring impedance dispersion compensation and a cross-type impedance matching network. The rectifier has an ultra-high power conversion efficiency. The compensation network employs two parallel transmission lines to counteract the nonlinear shift of the diode input impedance caused by frequency variation. Additionally, the cross-over impedance matching network enhances matching and minimizes losses. After rigorous theoretical analysis and simulation, the rectifier is fabricated.

Abstract:
In this paper, an ultra-wide band 0.18 μm CMOS common-gate low-noise amplifier (LNA) is presented. Designed in the ultra-wide band frequency range of 3.1–10.6 GHz, it uses a current-reused technique with modified input matching. This approach allowed obtaining a flat broadband gain of 12.75 ± 0.83 dB with an input reflection coefficient less than -5.5 dB, an output reflection coefficient less than -7 dB, and a noise figure less than 3.7 dB. Furthermore, the proposed low-power LNA consumes only 12.14 mW (excluding buffer) from a 1.2 V supply voltage.

To solve the problem consisting in the great degradation of the power conversion efficiency (PCE) of a multi-band rectifier according to the RF input power range because the available RF input power range is different according to the frequency band, the proposed dual-

Abstract:
The ever growing demand for higher data rates and the heavy usage of wireless communication devices have created frequency congestion on certain bands of the radio spectrum. The push has been towards new standards that can quench this thirst for data capacity and more space on the spectrum. This has led to added complexity and cost for radio platforms. In particular, the increase in the number of antennas, switch banks and pre-select filters have made it challenging to implement these platforms cost-effectively. Therefore, concepts such as software-defined radio(SDR) and cognitive radio(CR) ha
