power gate choice for low power

[fragnen]

What is better to use as power gate between pmos and nmos and why?

The choice depends on the voltage level. PMOS transistors are more suitable for applications where the load is connected to the high-voltage rail. PMOS transistors can be more expensive and generally have larger physical sizes compared to NMOS transistors. They might not be as efficient as NMOS transistors in low-voltage applications.MOS transistors are commonly used as low-side switches in power management circuits. They are more efficient and have better performance characteristics in low-voltage applications. NMOS transistors have higher ON resistance compared to PMOS transistors. It may lead to more power dissipation and heat generation in high-voltage applications. Here is a design of a Buck Converter using MOSFET Gate Driver in Proteus. You can check it out.
