How can the corner frequency of a MOSFET amplifier be increased?

There are a few ways to increase the corner frequency of a MOSFET amplifier: Use a MOSFET with a lower gate-drain capacitance .The gate-drain capacitance is a parasitic capacitance that exists between the gate and drain terminals of a MOSFET. It is caused by the overlap of the gate and drain regions. The lower the gate-drain capacitance, the higher the corner frequency. Use a MOSFET with a higher source resistance .The source resistance is the resistance of the source lead of the MOSFET. The higher the source resistance, the higher the corner frequency.

How to Calculate Critical Frequency of Mosfet?

Critical Frequency of Mosfet calculator uses Critical Frequency in decibles = 10*log10(Critical Frequency) to calculate the Critical Frequency in decibles, The Critical Frequency of Mosfet formula is defined as an important parameter for high-frequency MOSFET circuits. If the operating frequency of the circuit is above the critical frequency, the Miller capacitance will cause the gain of the circuit to decrease and the bandwidth of the circuit to narrow. Critical Frequency in decibles is denoted by Ap(dB) symbol.

How to calculate Critical Frequency of Mosfet using this online calculator? To use this online calculator for Critical Frequency of Mosfet, enter Critical Frequency (Ap) and hit the calculate button. Here is how the Critical Frequency of Mosfet calculation can be explained with given input values -> 6.0206 = 10*log10(4).

FAQ

What is Critical Frequency of Mosfet?
The Critical Frequency of Mosfet formula is defined as an important parameter for high-frequency MOSFET circuits. If the operating frequency of the circuit is above the critical frequency, the Miller capacitance will cause the gain of the circuit to decrease and the bandwidth of the circuit to narrow and is represented as Ap(dB) = 10*log10(Ap) or Critical Frequency in decibles = 10*log10(Critical Frequency). Critical Frequency of a MOSFET is the frequency at which the Miller capacitance of the MOSFET begins to dominate the circuit performance.
