| چکیده | ||
| در این مقاله یک تقویتکننده کمنویز تمامتفاضلی جدید برای کاربردهای فراپهنباند ارائه شده است. تقویتکننده پیشنهادشده شامل طبقهی ورودی گیتمشترک برای بهبود تطبیق امپدانس و طبقه دوم سورس مشترک برای افزایش بهره و کاهش نویز تقویتکننده است. همچنین از فیدبک ترانزیستوری موازی-موازی برای افزودن درجه آزادی در انتخاب ترارسانایی ترانزیستور ورودی و بهبود پهنای باند و خطسانی استفاده شده است. تقویتکننده کمنویز پیشنهادشده بر اساس فنّاوری µm 18/0 CMOS RF-TSMC طراحی و با استفاده از نرمافزار ADS شبیهسازی شده است. این تقویتکننده در پهنای باند GHz 7-4، دارای بهره توان مسطح (S21) dB 25/0± 17، عدد نویز کمتر از dB 7/2، تلفات بازگشتی ورودی (S11) کمتر از dB 10- و خطسانی (IIP3) dBm 1- است. توان مصرفی آن نیز mW 5/8 از منبع تغذیه V 75/0 است. | ||

| A Low Voltage, High Gain, Fully Differential CMOS Low-Noise Amplifier for Ultra-Wideband Applications | ||
| چکیده [English] | ||
| In this paper, a novel fully differential low-noise amplifier (LNA) has been presented for ultra-wideband (UWB) applications. The proposed LNA consists of a common-gate input stage to improve the input impedance matching and a common source second stage to amplify the input signal while reducing the noise figure (NF). A shunt-shunt transistor feedback is also applied to add a degree of freedom to the trans-conductance (gm) of the input stage and to achieve wide bandwidth and high linearity. The proposed LNA is designed and simulated in the RF-TSMC 0.18 μm CMOS process technology by the Advanced Design System (ADS). The simulation results show a flat power gain (S21) of 17±0.25 dB, a noise figure less than 2.7 dB, an input (S11) less than -10 dB and high linearity with input third-order intercept point (IIP3) of -1 dBm, over the frequency band of 4-7 GHz. The proposed LNA has low power dissipation of 8.5 mW from the 0.75 V power supply. | ||
