Cell Capacitance Solution

Follow our step by step solution on how to calculate Cell Capacitance?

FIRST Step Consider the formula

C cell = \frac{C bit \cdot 2 \cdot ΔV}{V dd - (ΔV \cdot 2)}

Next Step Substitute values of Variables

∴

C cell = \frac{12.38pF \cdot 2 \cdot 0.42V}{2.58V - (0.42V \cdot 2)}

Next Step Convert Units

∴

C cell = \frac{1.2E-11F \cdot 2 \cdot 0.42V}{2.58V - (0.42V \cdot 2)}

Next Step Prepare to Evaluate

∴

C cell = \frac{1.2E-11 \cdot 2 \cdot 0.42}{2.58 - (0.42 \cdot 2)}

Next Step Evaluate

∴

C cell = 5.97655172413793E-12F

Next Step Convert to Output's Unit

∴

C cell = 5.97655172413793pF

LAST Step Rounding Answer

∴

C cell = 5.9766pF

How to Evaluate Cell Capacitance?

Cell Capacitance evaluator uses Cell Capacitance = (Bit Capacitance*2*Voltage Swing on Bitline)/(Positive Voltage-(Voltage Swing on Bitline*2)) to evaluate the Cell Capacitance, The Cell Capacitance formula is defined as how quickly the membrane potential can respond to a change in current. A capacitor is made up of two conducting materials separated by an insulator in the case of a cell, the extracellular and intracellular fluids are the conductors, and the lipid membrane is the insulator. Cell Capacitance is denoted by C_cell symbol.

How to evaluate Cell Capacitance using this online evaluator? To use this online evaluator for Cell Capacitance, enter Bit Capacitance (C_bit), Voltage Swing on Bitline (ΔV) & Positive Voltage (V_dd) and hit the calculate button.

FAQs on Cell Capacitance

What is the formula to find Cell Capacitance?

The formula of Cell Capacitance is expressed as Cell Capacitance = (Bit Capacitance*2*Voltage Swing on Bitline)/(Positive Voltage-(Voltage Swing on Bitline*2)). Here is an example- 6E+12 = (1.238E-11*2*0.42)/(2.58-(0.42*2)).

How to calculate Cell Capacitance?

With Bit Capacitance (C_bit), Voltage Swing on Bitline (ΔV) & Positive Voltage (V_dd) we can find Cell Capacitance using the formula - Cell Capacitance = (Bit Capacitance*2*Voltage Swing on Bitline)/(Positive Voltage-(Voltage Swing on Bitline*2)).
