Keywords:
Broadband, LAN, Common Source, RFAbstract
This paper presents the design of a broadband Low Noise Amplifier (LNA). The work presented by the structure is capable of operating on a frequency band stretching from 0.8GHz to 2.5GHz i.e. covering most of the high speed data applications. Common source LNA design is offered in this paper. The design is implemented using 0.18�m CMOS process with a supply voltage of 1.3V. The Cascade LNA achieves 12.8 dB (min.) gain, 0.44 dB (min.) NF over operating frequency spectrum upholding high degree of stability factor. LNA presented in this paper consumes 19mW of power.
