  • Nonlinear and memory effects in RF power amplifiers significantly impact signals in modern communication systems.

    To judge the expected nonlinearity of an Amplifier during the design process two-tone simulations are used, as they have similar characteristics to modern modulations schemes. For more advanced amplifier configurations it is unclear how two-tones simulations relate to real signals. To study this behavioral models of the amplifier can be used to reduce computing demand.

    The student will use a behavioral amplifier component  provided in ADS to model a transistor core. Then modulation schemes will be applied to the model and the response studied.

    Tasks:

    -Understand the ADS provided model

    -Extract needed parameters from provided core and compare model to layout

    -Model different modulations and compare behavior to two tone simulations

    Requirements:

    -Good understanding of circuits

    -Interest in modeling and Power Amplifiers
