Variables Used
Base Collector Delay Time - (Measured in Second) - Base Collector Delay Time refers to the additional time taken by the signal to propagate through space charged region of base collector junction.
Emitter Collector Delay Time - (Measured in Second) - Emitter collector delay time is defined as the transit time across the base-collector depletion region or space.
Collector Charging Time - (Measured in Second) - Collector charging time refers to the time taken for the minority carriers in the base region of a BJT to be swept out of the collector region after the transistor is turned off.
Base Transit Time - (Measured in Second) - Base transit time is the average time the minority carriers need to traverse the quasi-neutral region in the base.
Emitter Charging Time - (Measured in Second) - Emitter charging time is defined as drift in the motion of the charged particles induced by a field when you forward bias the emitter junction you get a large diffusion.
