MOS transistor conduction characteristics

MOS transistor conduction characteristics

Conduction means to act as a switch, equivalent to the switch being closed.

The characteristic of NMOS is that Vgs will conduct when it exceeds a certain value, making it suitable for use in the case of source grounding (low end drive), as long as the gate voltage reaches 4V or 10V.

The characteristic of PMOS is that when Vgs is less than a certain value, it will conduct, which is the case when using VCC connected to the source electrode (high-end drive). However, although PMOS can be easily used as a high-end driver, due to high conduction resistance, high price, and limited replacement options, NMOS is usually still used in high-end drivers
