Abstract :
Design, development and simulation results of an integrated 4 GHz ultra wide band CMOS low noise amplifier (LNA) are presented. The proposed amplifier is designed to use for RFID systems, especially in receiver applications. The amplifier employs an input band pass Chebyshev filter. It provides a forward gain (S21) of 18.42 dB and reverse gain (S12) of 4.01 dB with input reflection of only 9.9 dB while drawing 30 mW from a 1.5 V supply. A detailed analysis of the LNA architecture is presented, including a discussion on the effects of induced S-parameter analysis, phase shift and Smith chart analysis, and power transmission characteristics.
