Simulation Results

We research the new thin film transformer equivalent circuit modeling, simulate and modify the traditional estimate formula of the transformer equivalent circuit parameters, in order to attain the automatic extraction of thin film transformer parameters. This paper used MATLAB and Agilent ADS on the thin film transformers for the S parameter simulation. The simulation results show the estimation has better accurate and universal, it also shows the effect of different number of turns and thin film materials on the properties of thin film transformer.

Analytical Expressions

Analytical expressions for the PM noise in FET oscillators are derived in terms of the FET equivalent circuit elements and the passive circuitry. Efficient methods to reduce the PM noise in fundamental and in harmonic modes are suggested and implemented. The effects of the different FET equivalent circuit parameters on large-signal, small-signal, and noise behavior of FET oscillators are investigated. Finally, the effects of harmonic signal on the output noise power and on the phase noise at both fundamental and harmonic frequencies are determined.
