## Gate Capacitance Solution

STEP 0: Pre-Calculation Summary
Formula Used
channel_charge = Gate Capacitance*(Gate to Channel Voltage-Threshold voltage)
Qchannel = Cg*(Vgs-VT)
This formula uses 3 Variables
Variables Used
Gate Capacitance - Gate Capacitance is the capacitance of the gate terminal of a field-effect transistor. (Measured in Farad)
Gate to Channel Voltage - Gate to Channel Voltage is the voltage across (Measured in Volt)
Threshold voltage - Threshold voltage of transistor is the minimum gate to source voltage that is needed to create a conducting path between the source and drain terminals. It is an important factor to maintain power efficiency. (Measured in Volt)

## Explain how binary number can give a signal or convert into a digital signal?

The binary number consists of either 0 or 1, in simple words number 1 represents the ON state, and number 0 represents the OFF state. These binary numbers can combine billion of machines into one machine or circuit and operate those machines by performing arithmetic calculations and sorting operations.
