MOSFET
Which combination lists the main components of leakage current in a MOSFET in the off state?
- ASubthreshold leakage, gate leakage and junction leakage
- BOnly photocurrent
- CNo leakage current flows at all
Show answer and explanation
Answer: A. Subthreshold leakage, gate leakage and junction leakage
Even an off MOSFET carries subthreshold leakage below threshold, gate leakage through the gate insulator, and junction leakage through the source and drain junctions (including GIDL). These increase with scaling and are a major source of standby power consumption.
