Transistor question

[unplebeian]

1. Homework Statement

What does a capacitor across the base and collector of the transistor do? Apparantly adding a cap (1uF) will slow it down. Can anyone explain how?

2. Homework Equations



3. The Attempt at a Solution

 

[CEL]

Have you already studied feedback? The capacitor provides a feedback of high frequencies from the collector to the base.

Can you please elaborate or provide me with a reference. I have a text by Gaussi on Analog devices. What section does this come in (miller capacitance??)

I don't know your textbook. Miller capacitance is a way of analyzing the effect of the feedback provided by your capacitor.
