Explain the three different types of modes of operation of pMOS transistor
March 05, 2024
- The pMOS transistor in Figure 4 operates in just the opposite fashion. The n-type body is tied to high potential, junctions of p-type source and drains are normally reverse-biased.
- When the gate has high potential, no current flows between drain and source.
- When the gate voltage is lowered by a threshold Vt, holes are attracted to form a p-type channel beneath the gate, allowing current to flow between drain and source.
