Abstract

A LNA (Low Noise Amplifier) circuit with high centre frequency and ultra wide bandwidth is designed. IBM 90nm CMOS process is used to design this circuit. Centre frequency of this LNA circuit is 18.3 GHz. At the centre frequency gain is 14.38 decibel. 5.7 GHz is the-3 dB bandwidth of this LNA circuit. It can be operated from around 14.2GHz to around 19.9 GHz with considerably high gain. Performance of this LNA circuit is verified by simulation. This circuit has a power consumption of this circuit is 64.63 micro-watt. Required supply voltage for this LNA circuit is 1.4V.
