This thesis discusses design of narrowband low noise amplifiers for multi¬standard applications. The target of this work is to design a low noise ampli¬fier(LNA) for DCS1800 and Bluetooth standard frequency bands. Various designs for narrowband multi-standard LNAs have been studied and a new design for tunable multi-standard LNA has been presented and designed using accumulation mode MOS varactors. As this design includes on-chip spiral inductors, the design, modelling and layout of on-chip inductors have been discussed briefly. The tool used for this purpose is ASITIC. Also ESD protection techniques for RF circuits and their effect on LNA per¬formance has been discussed. Finally fully differential LNA has been designed in O.35um AMS thick metal CMOS process using Cadence SpectreRF. The design also includes ESD pro¬tection at the input of LNA.
