CMOS Low Noise Amplifier Design for IMT-2000

IMT-2000용 CMOS 저잡음증폭기 설계

This paper describes a CMOS low noise amplifier (LNA) with bias current reusing architecture intended lot use in the front-end of IMT-2000 receiver. It has been implemented in a 0.35$\mu\textrm{m}$ CMOS process with two poly and four metal layers. In order to accuracy of simulation, we considered a bonding wire and a pad effect and used the measurements of capacitors and on-chip inductors which implemented in the same process. The LNA has a forward gain (S21) of 17 ㏈ and a noise fjgure of 1.26 ㏈. And it has a third-order intermodulation intercept point (IP3) of +3.15 ㏈m and a 1㏈ compression point (P1㏈) of -16 ㏈m, input referred, respectively. The power consumption is 19 ㎽ from a 3V supply.
