Leakage Current
- Current that flows in a device unintentionally when no voltage is applied.
- Can occur due to various mechanisms:
- Tunneling: Electrons tunnel through barriers instead of flowing normally.
- Surface leakage: Current flows along the surface of the device rather than through the intended path.
- Junction leakage: Reverse current flows through diodes or semiconductor junctions.
Causes of Leakage Current:
- Defects in the material, such as impurities or crystal imperfections
- High-voltage stress
- Temperature variations
- Process variation
Effects of Leakage Current:
- Increased power dissipation: Leakage current wastes energy and can increase device temperature.
- Reduced device reliability: High leakage current can lead to device failure.
- Circuit malfunctions: Leakage current can interfere with circuit operation, causing noise or logic errors.
Methods to Reduce Leakage Current:
- Use high-quality materials: Reduce defects and impurities.
- Optimize device design: Minimize surface leakage and junction area.
- Employ leakage reduction techniques:
- Body biasing: Adjust the voltage levels to reduce reverse current in junctions.
- Oxide scaling: Reduce the thickness of the gate oxide layer to suppress tunneling.
- Gate bias engineering: Optimize gate voltage to minimize leakage.
Measurement of Leakage Current:
- Use a picoammeter or low-current measuring device.
- Apply a small voltage across the device and measure the current.
- Compare the measured leakage current to the specified limits.
