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?
unplebeian said: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??)
The capacitor helps to stabilize the voltage at the base and collector of the transistor, preventing fluctuations and ensuring the transistor operates within its desired range.
The capacitor helps to smooth out any sudden changes in voltage at the base and collector, which can improve the overall stability and accuracy of the transistor's output.
Yes, a capacitor can be used in various transistor circuits, including common-emitter, common-base, and common-collector configurations.
The value of the capacitor will depend on the specific circuit and desired performance. However, smaller capacitors with lower capacitance values are typically used in these types of circuits. As for the type, ceramic capacitors are commonly used due to their stability, low cost, and compact size.
In certain cases, a capacitor may introduce unwanted noise or instability into the circuit. It is important to carefully select the appropriate value and type of capacitor for the specific transistor circuit to avoid any negative effects.
