How to Calculate Gate Capacitance?
Gate Capacitance calculator uses channel_charge = Gate Capacitance*(Gate to Channel Voltage-Threshold voltage)
to calculate the Channel Charge, The Gate Capacitance formula is defined as the capacitance of the gate terminal of a field-effect transistor. It can be expressed as the absolute capacitance of the gate of a transistor, or as the capacitance per unit area of an integrated circuit technology, or as the capacitance per unit width of minimum-length transistors in a technology. Channel Charge and is denoted by Qchannel symbol.
How to calculate Gate Capacitance using this online calculator? To use this online calculator for Gate Capacitance, enter Gate Capacitance (Cg), Gate to Channel Voltage (Vgs) and Threshold voltage (V_{T}) and hit the calculate button. Here is how the Gate Capacitance calculation can be explained with given input values -> -168 = 4*(8-50)
