  • Abstract
    The 3-db cutoff frequency and the gain-bandwidth product are calculated for the common-emitter current gain. The calculation is made in a simple manner and in general form so as to apply to all transistors. The gain-bandwidth product is shown to be determined by the transit time across the base and the space-charge capacitances. The gain-bandwidth product reaches a maximum for drift transistors at a critical current. This current is given.
