چکیده
This paper presents a design of Low Noise Amplifier (LNA) for Cognitive Radios (CRs) receiver and it operates from 50 MHz to 5 GHz. The proposed design is consisted of two stages, the first one is a combination of cascode with common gate stage to improve the gain, power consumption, and the input matching. The second stage is a common source (CS) for canceling the noise and distortion of CG of the first stage. This design achieves a noise figure 4.1-4.8 dB, input reflection coefficient less than 11 dB, output reflection coefficient below -10dB, the power gain from 10.2 dB to 12.5 dB and the consummation power 7.14 mW supplied from 1 V. The proposed LNA is designed using 0.18 μm CMOS technology.

An area-efficient 60-GHz wake-up receiver (WuRx) using reconfiguration techniques of multistage low-noise amplifiers (LNAs) is presented. The gain stages of the 60-GHz LNA are reused as the envelope detectors for the wake-up receiver. Therefore, the bulky components such as extra switches between the wake-up receiver and the LNA, additional antennas, and excess input matching network can be rem...
