This discourse used 45nm CMOS technology to design a Low noise amplifier for a Noise figure < 2dB and gain greater than 13dB at the 60GHz unlicensed band of frequency. A single stage, primary cascode LNA is modeled and its small signal model is analyzed. Common source structure is hired in the driver stage to escalate the output power with single stage contours. To enhance small signal gain, simple active transistor feedback and cascode feedback configurations are designed and appended to the basic LNA. In addition to this, current re-use inductor is designed and added to the cascode amplifier which is deliberated to give low power and low noise figure. Small signal analysis of simple active transistor feedback and current re-use inductor has been presented. The measurement results indicated that the input match and the output gain at 60GHz achieves -8dB and 13dB respectively with the supply voltage of 900mV. The frequency response obtained is a narrow band response with 6GHz of bandwidth. The circuit is simulated by Cadence Virtuoso tool. The layout of the related circuit is drawn by means of the Virtuoso Layout editor with total size of 0.1699μm2.

<span>This paper presents a concurrent dual-band CMOS low noise amplifier (LNA) at operating frequency of 2.4 GHz and 5.2 GHz for WLAN applications. The proposed LNA employed cascode common source to obtain high gain using 0.13-µm CMOS technology. The concurrent dual-band frequencies are matched using LC network band-pass and band-stop notch filter at the input and output stages. The filters help to shape the frequency response of the proposed LNA. The simulation results indicate that the LNA achieves a forward gain of 21.8 dB and 14.22 dB, input return loss of -18 dB and -14 dB at 2.4 GHz and 5.2 GHz, respectively. The noise figure of 4.1 dB and 3.5 dB with the input third-order intercept points 7 dBm and 10 dBm are obtained at 2.4 GHz and 5.2 GHz, respectively. The LNA dissipates 2.4 mW power at 1.2 V supply voltage with a chip size of 1.69 mm2.</span>

A CMOS low noise amplifier (LNA) for ultra-wideband (UWB) wireless applications is presented in this paper. The proposed CMOS low noise amplifier (LNA) is designed using common-gate (CG) topology as the first stage to achieve ultra-wideband input matching. The common-gate (CG) is cascaded with common- source (CS) topology with current-reused configuration to enhance the gain and noise figure (NF) performance of the LNA with low power. The Buffer stage is used as output matching network to improve the reflection coefficient. The proposed low noise amplifier (LNA) is implemented using CADENCE Virtuoso Analog and Digital Design Environment tool in 90nm CMOS technology. The LNA provides a forward voltage gain or power gain (S21) of 32.34dB , a minimum noise figure of 2dB, a reverse-isolation (S12) of less than - 38.74dB and an output reflection coefficient (S22) of less than -7.4dB for the entire ultra-wideband frequency range. The proposed LNA has an input reflection coefficient (S11) of less than -10dB for the ultra-wideband frequency range. It achieves input referred 1-dB compression point of 78.53dBm and input referred 3-dB compression point of 13dBm. It consumes only 24.226mW of power from a Vdd supply of 0.7V.
