Abstract :
A method for loop circuit stability analysis is introduced through investigating its closed-loop admittance and open-loop impedance. This method has wider adaptability and less limitation than the traditional approach which uses open-loop power-wave transfer function. A 6-GHz HBT oscillator is designed to verify this method. The measurement result shows the effeteness of the proposed method while the traditional method fails.
