Which one of the following bipolar transistors has the highest current gain bandwidth Product (fr) for similar geometry?-A-NPN germanium transistorB-NPN silicon transistorC-PNP germanium transistorD-PNP silicon transistor-B-NPN silicon transistor

Question

APTITUDE CRACK · Accepted Answer

B NPN silicon transistor Answer should be A because the current gain is high for germanium relating to mobility of Ge higher than si for constant bandwidth.
