Total Transit Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Transit Time = Base Transit Time+Collector Depletion Region
τ_tt = τ_b+τ_ttc
This formula uses 3 Variables

Variables Used

Total Transit Time - (Measured in Second) - Total Transit Time in a BJT is the duration for charge carriers to traverse the transistor, covering base and collector-emitter region transit times.
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.
Collector Depletion Region - (Measured in Second) - The Collector Depletion Region Transit Time in a BJT refers to the duration it takes for charge carriers to travel across the collector-emitter region of the transistor.

STEP 1: Convert Input(s) to Base Unit

Base Transit Time: 10.1 Microsecond --> 1.01E-05 Second (Check conversion here)
Collector Depletion Region: 8.9 Microsecond --> 8.9E-06 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

τ_tt = τ_b+τ_ttc --> 1.01E-05+8.9E-06

Evaluating ... ...

τ_tt = 1.9E-05

STEP 3: Convert Result to Output's Unit

1.9E-05 Second -->19 Microsecond (Check conversion here)

FINAL ANSWER

19 Microsecond <-- Total Transit Time
