"WebN channel-only semiconductors. The most efficient MOSFET designs use N-channel MOSFETs on both the high side and low side because they typically have a third of the ON resistance of P-channel MOSFETs. This requires a more complex design since the gates of the high side MOSFETs must be driven positive with respect to the DC supply rail. " - How do p channel mosfets work

P-Channel MOSFET Basics - Learning about Electronics

WebIn a MOSFET, the channel & gate are separated through a thin SiO2 layer and they form a capacitance that changes with gate voltage. So, MOSFET works like a MOS Capacitor that is controlled through the input gate to source voltage. Thus, MOSFET can also be used as a voltage-controlled capacitor. WebUsing a p-channel MOSFET may place some severe restraints on the gate drive, since the gate must be close to V DD (Figure 1b). To return gate control to a more acceptable logic format, add an n-channel MOSFET (Figure 3). Using an n-channel MOSFET in this way simplifies the gate drive for a high-voltage, high-side, p-channel MOSFET.
