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.
Can you use a fet as a capictor?
No. Not for any practical capacitor value. There is an inherent capacitance between the gate and the drain/source channel, but it's only a few picofarads.
What is the difference betbeen capacitor and condensor?
A: Both nomenclature are indicator of capacitance it can be used both ways. However the predominate usage is capacitor since it resemble capacitance
What is the miller effect in simple terms?
A: That becomes evident while the driving source i limited in current driving abilities the voltage increases the phenomenon occurs known as the miller effect. Once the threshold voltage is passed it begins to draw increasingly heavier drain current with respect to the gate. As the drain rises the trans conductance rises rapidly to saturation. concurrent with the rise in gain the once low feedback capacitance now swells to enormous proportions appearing as an additional to the input capacitance. cin=ciss+[1+av]cgd ciss= gate source in cap cgd=m gate drain capacitance av= voltage gain
How many gates are used in XOR gate?
1 gate.
What is the importance gate capacitance in CMOS device?
For the gate to change state, the gate capacitance must be charged or discharged. Since the transistor driving the gate has a certain amount of output impedance (resistance), this together with the gate capacitance forms an RC network. The gate capacitance must charge through the driver's output impedance, and this takes time. So, gate capacitance limits the maximum speed at which the device can be operated. Decrease the capacitance, and you can clock the device faster!

What are CMOS parameters?
Gate Area, gate capacitance per unit area, gate capacitance, parasitic capacitance, carrier density, channel resistance, gate delay, max operating freq, saturation current, power dissipation, current density, power speed product
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 junction capacitance and transition capacitance the same?
Junction capacitance is used to take the ripple out of DC circuits primarily. The other is used in voltage doublers or step ups as a storage.

How much capacitance is used in general circuit?
You need to be little more specific to get an accurate answer. Capacitance in which circuit? Thanks.
How does the Switching diode used in television tuning?
A: Those diodes are used as a variable capacitance whereby applying a voltage changes the capacitance which effect the frequency of the tuning circuit
