Definition of a capacitance in mosfet?
Capacitance in mosfet is of three types: gate capacitance diffusion capacitance routing capacitance Gate capacitance: limits the speed of the device t which it can be operated Diffusion capacitance: It is the capacitance due to charge carriers between drain and source. Routing capacitance: It is the capacitance of the metal which is deposited on the top of oxide layer.
How do you calculate the stray capacitance?
stray capacitance calculation
What is the effect of dielectric on the capacitance of a capacitor?
Any variation of the charge within a p-n diode with an applied voltage variation yields a capacitance wich must be added to the circuit model of a p-n diode. The capacitance associated with the charge variation in the depletion layer is called the junction capacitance, while the capacitance associated with the excess carriers in the quasi-neutral region is called the diffusion capacitance. Both types of capacitances are non-linear so that we will derive the small-signal capacitance in each case. We will find that the junction capacitance dominates for reverse-biased diodes, while the diffusion capacitance dominates in strongly forward-biased diodes. The total capacitance is the sum of both.
What is meant by transistion and space charge capacitance of a diode?
Diffusion capacitance is the capacitance due to transport of charge carriers between two terminals of a device. - Amog This diffusion capacitance is due to depletion capacitance which is a function of forward bias applied to emitter junction of a transistor and due to diffusion capacitance which a function of transconductance of the transistor. Its value is 100 pF. Tirupanyam B.V
Which junction has least junction capacitance?
point contact has the least junction capacitance
What is the capacitance when Q equals fifty times ten to the negative sixth?
C = Q/V; capacitance = charge / voltage. Therefore, you would also have to know the voltage.
In the inverted region of Marcus, what unique characteristics or phenomena can be observed?
In the inverted region of Marcus, unique characteristics or phenomena such as negative differential resistance and negative differential capacitance can be observed. These phenomena involve the decrease in current or capacitance with increasing voltage, which is opposite to the typical behavior in electronic devices.
When the frequency in Hertz and the reactance positive or negative in Ohms are known can you determine component values such as inductance or capacitance?
Positive

How introduction of a die-electric increases the capacitance of the capacitor?
By connecting a capacitor in series the total dielectric thickness between the positive and negative terminals of the source, since you double dielectric thickness has effectively doubled, the total capacitance is one half of either capacitors.
How do you calculate the stray capacitance?

What is the type of capacitance effect exhibited in P-N junction when it is reverse biased?
1. Transition capacitance 2. Diffusion capacitance 3. Space charge capacitance 4. Drift capacitance
What is the difference between self capacitance and mutual capacitance in the context of capacitive touch technology?
Self capacitance refers to the capacitance between the touch sensor and the ground, while mutual capacitance refers to the capacitance between two different touch sensors. In capacitive touch technology, self capacitance is used for single-touch detection, while mutual capacitance is used for multi-touch detection.
What is the difference between capacitance and stray capacitance?
Capacitance is an ability to store an electric charge. "If we consider two same conductors as capacitor,the capacitance will be small even the conductors are close together for long time." this effect is called Stray Capacitance.
Effects of stray capacitance in ac fan out?
due to the load gates capacitance values,there is a increased load capacitance on the driving gate

Are arteries often referred to as capacitance vessels?
No. Capacitance vessels refer to site where most volume of blood is found. Veins are capacitance vessels.
