Abstract:
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.
