Operating Principle and Construction At the heart of the pmos mosfet is a structure featuring a p-type substrate, two n+ regions serving as source and drain, and an insulating oxide layer capped by a gate electrode. When a negative gate-to-source voltage is applied relative to the source, it attracts holes and repels electrons, creating a conductive p-channel beneath the oxide.

The saturation region, where the current becomes relatively constant despite increasing drain voltage, is the preferred zone for switching and high-gain amplification tasks. Careful balancing of these metrics ensures optimal performance for the intended application.
Layout Considerations and Parasitics. This enhancement mode behavior contrasts with depletion-type variants, which conduct at zero gate voltage and require positive bias to pinch off the channel.

This regime is valuable for analog applications such as voltage followers or small-signal amplifiers. On-resistance impacts conduction losses in power applications, while gate capacitance influences switching speed and drive requirements.
