Abstract :
In this work a 5-GHz receiver front-end is designed for the application of wireless sensor networks. The circuit topology is chosen available for low supply voltage below 1V. The stability condition of the LNA circuit is ensured by adding reactive components. Total power consumption of the fabricated circuit is 0.86mW, of which 0.7mW goes to the LNA stage. The measured return loss and conversion gain are 11dB and 25dB, respectively. The noise figure is 12dB and the IIP3 is around -6.5dBm
