Mosfet Drive Circuit Layout Design

Because the Mosfet Drive Circuit Layout Design will have parasitic inductance, and the parasitic inductance and the junction capacitance of the Mosfet will form an LC oscillation circuit. If the output terminal of the driving chip is directly connected to the gate of the Mosfet tube, then on the rising and falling edges of the…

Mosfet Drive Circuit Design

It is generally believed that MOSFET (MOS tube) is driven by voltage and does not require driving current. However, there is a junction capacitance between the G pole and the S pole of the Mosfet, and this capacitance will make it difficult to drive the MOS. The three capacitors in the figure below are the…
