LNA is one of the most important building blocks in the front end of the wireless communication systems. Amplification of weak signal and attenuation in noise level is a key role of LNA. In recent years valuable research is done on CMOS LNA design in on improvement of low power consumption, low noise figure, high gain, smaller space and low supply voltage. This paper illustrates a review work r...

In this paper, a 5.2GHz low noise amplifier in 0.25um CMOS utilizing inter-stage matching is designed. Two realizations for a low value of inductor within the LNA are implemented. The measurement results are 7dB gain and 5.86dB noise figure is achieved for the on-chip inductor realization, and 8.3dB gain and 5.74dB noise figure is achieved for the bond-wire inductor realization.

General conditions for minimizing the noise figure of any linear two-port are reviewed before considering the specific case of a MOSFET low-noise amplifier (LNA). It is shown that the minimum noise figure cannot be obtained over an arbitrarily large bandwidth with networks of low order. For narrowband operation, however, one may construct simple amplifiers whose noise figure and power gain are ...

Formulas for the noise figure, and the minimum uoisefigure of a multi-link distributed amplifier have been developed. In addition, a relatively simple approximation formula has been devised that predicts the minimum noise figure of a practicaf amplifier design with good accuracy np to frequencies of 9 GHz. Finafly, after the dependence of the noise characteristics on the circnit parameters is d...

This paper presents a new ultra-wideband LNA which employs the complementary derivative superposition method in noise cancellation structure. A pMOS transistor in weak inversion region is employed for simultaneous second- and third-order distortion cancellation. Source-degeneration technique and two shunt inductors are added to improve the performance at high frequencies. The degeneration induc...

Low Noise Amplifier, CMOS, Noise Canceling, Technique. This paper presents a 0.8V, 3.6GHz narrow band CMOS low noise amplifier (LNA). A current-reused technique is employed to increase the gain of LNA. Also, in order to achieve low noise figure, a noise canceling technique is used in the output stage. The high gain LNA was designed and simulated in 0.13 μm CMOS process. A gain of 27 dB at 3.6GH...

This paper presents a wideband low-noise amplifier (LNA) designed to be used as the first stage of the receiver in the Square Kilometer Array radio telescope. The LNA design procedure and its layout features are discussed. The noise figure optimization procedure determines the signal-source resistance that results in reduced noise figure. When used in the radio telescope, the required signal-so...
