Abstract

Cognitive radio is well known as an ultra-wideband communication system that intelligently optimizes the available frequency spectrum by implementing the dynamic spectrum monitoring method. This system can meet the needs of field communication systems well and be used in most operational equipment. In this paper, to realize this system, using the cross coupling of two active inductors consisting of common gate topology and feedback, in a differential structure, a novel ultra-wideband low noise amplifier is designed. The use of active inductor, in addition to increasing the amplifier bandwidth and reducing the chip area, due to its high quality factor, it also has the ability to adjust the inductance and frequency. In addition to input matching in the entire frequency bandwidth, this structure increases the transconductance of the transistors with the proposed structure and reduces the power consumption and the noise figure of the circuit. The simulation results show that in the frequency range of 50 MHz to 10 GHz, this structure has a better input matching than -10 dB, power gain of 10.4 dB, noise figure variations of 3-6.7 dB and a third-order intercept point is -4 dBm. The proposed LNA consumes 9.29 mW from a 1.8 V power supply.
