Silas stared. He put his hand near the board. He could feel history in the warmth. The crude point-contacts buzzed with the static of 1947, of Shockley’s betrayal and Bardeen’s quiet genius. The planar transistors hummed with the clean certainty of the 1960s space race. The MOSFETs whispered of the home computer revolution. The nanoscale finFETs vibrated with the frantic energy of the smartphone era.
Think of a BJT like a water valve that you turn by pushing a lever (using effort/current). Think of a FET like a valve you turn with a handle—once it's in position, it takes no effort to hold it there (voltage). alltransistors
And each one, in its own distorted, leaky, noisy way, answered: Yes. Silas stared
