This thesis studies a cascaded low noise amplifier which is composed of stages of amplifiers for the application in modern RF transceivers. Design considerations on power consumption, transducer gain, and noise factor of the amplifier were carefully considered. Special design consideration on the analytical equations to estimate noise factor of the amplifier has been validated with high accuracy. The contents of this thesis are partitioned as follows: Chapter one is to describe the motivation of this research, relevant literature review, and research methodologies which is used in this research. Chapter two summarizes the fundamental knowledge for evaluating the circuit parameters of an amplifier and with emphasis on the noise properties. Chapter three describe the analytical design and simulation on the first stage of the amplifier, DC analysis, series resonance matching, parallel resonant matching, frequency response, and noise figure analysis. Chapter four is for the description of the second stage feedback inverting amplifier. Emphases were on the design and simulation of the DC analysis, the equivalent circuit archive, and noise figure analysis which includes the thermal noise source of the transfer function, power spectral density function, noise factor equation sequence composition, and the accuracy of the thermal noise parameters of the amplifier. Chapter five is on the simulation of a cascade amplifier composed of the above first and the second stage amplifiers. After three times of test and evaluation the amplifier has been transformed into a three-stage amplifier with adjustable power gain. Chapter six is composed of concluding remarks, outlines of accurate design methods, prospects and further studies of this thesis.
