چکیده مقاله :
امروزه یکی از مسائل مهم در سیستم‌های مخابرات سیار، داشتن عمر بالای باتری است. از این رو مسئله توان مصرفی، به عنوان یکی از چالش ها در عرصه طراحی مدارات فرکانس بالا نمایان است. در یک گیرنده فرکانس بالا بدلیل قرار گیری تقویت کننده کم نویز در طبقه اول گیرنده، این تقویت کننده اهمیت بسیار بالایی برای تعیین خطینگی و نویز در کل گیرنده دارد. در این مقاله یک تقویت کننده کم نویز برای استاندارد سیستم موقعیت یاب جهانی (GPS) طراحی شده است که نسبت به کارهای گذشته نویز تقویت کننده به نحوی کاهش داده شده و همچنین توان مصرفی آن به حداقل قدار خود رسیده است. روش کار به این صورت است که در تقویت کننده های سورس مشترک پایه سورس آنها با یک سلف وصل شده که نتیجتاً منجر به بهبود نویز مدار می‌شود. اما سلف استفاده شده باعث اشغال سطح تراشه می‌شود. از این رو در این مقاله از وجود سلف در wire-bond استفاده شده و نویز تقویت کننده کاهش یافته و همچنین سطح اشغالی تراشه بزرگ نشده است. گین، NF و همچنین امپدانس ورودی تقویت کننده پیشنهادی در بهترین حالت و بدترین حالت در گوشه های FF و SS محاسبه شده اند که ملاحظه می‌شود در این مقاله در مقایسه با کارهای قبلی نتایج بسیار مطلوبی به دست آمده است.
Today, one of the most important issues in mobile communication systems is having a long battery life. Therefore, the problem of power consumption appears as one of the challenges in the field of designing high frequency circuits. In a high-frequency receiver, due to the placement of the low-noise amplifier in the first stage of the receiver, this amplifier is very important to determine the linearity and noise in the entire receiver. In this paper, a low noise amplifier has been designed for the GPS standard. Compared to previous works, the noise of the amplifier has been reduced somehow, and its power consumption has reached its minimum value. The working method is that in common source amplifiers, their source base is connected with an inductor, which results in improving circuit noise. But the used inductor occupies the surface of the chip. Therefore, in this article, the existence of the inductor in wire-bond is used, and the noise of the amplifier is reduced, and the occupied area of the chip is not increased. Gain, NF, input impedance of the proposed amplifier have been calculated in the best case and the worst case in the corners of FF and SS, and it can be seen that in this article, compared to the previous works, very favorable results have been obtained.
