Abstract :
Design and simulation of an Ultra Wide Band Low Noise Amplifier for 10.8 to 20.1 GHz applications is presented. A CG-CS topology is adopted in this work. CG is used for input matching in the whole band of operation. Output of the CG is fed to the CS amplifier input to increase the gain of the overall amplifier. The circuit is designed in IBM 130 nm CMOS Technology and simulated in HSPICE RF. The simulated results of the circuit shows 10.2 dB of forward gain (S21) with a bandwidth of 9.3 GHz, -18 dB input return loss (S11), reverse isolation (S12) of -44 dB and -32 dB of output matching parameter (S22) at center frequency, 14 GHz. This circuit exhibits a Nf of 5.03 dB at center frequency and 5.44 dB of average Nf. ICP is -17.2 dBm at the center frequency. It consumes only 7.38 mW when driven from 1.2 V source.
