Local feedback stabilized emitter follower cascade |
摘要 |
When plural emitter follower cascaded transistors are employed as a buffer to drive a capacitive load wherein instabilities can occur. The capacitive loads can result in either ringing or oscillation within such a buffer. The invention relates to applying negative feedback around one or more emitter followers in the cascade. In the preferred embodiment a three stage cascade of emitter followers is employed with negative feedback connected around the penultimate stage.
