Charge Pumping
Charge pumping is a type of hot carrier measurement. It provides direct measurement of interface
states and an indication of electron and hole trapping.
The gate of the MOS transistor is connected to a pulse generator. The current (Icp) is caused by the
repetitive recombination of minority carriers with majority carriers at the silicon-silicon oxide
interface.
