Abstract
The input impedance of a n- stage Darlington configuration is analyzed by using the hybrid-II equivalent circuit. Instability arise for n ≥ 2 as a result of real part being negative at some frequencies. A single transistor can also be made to oscillate by connecting an external capacitor between emitter and ground.
