Self Induced Resistance in MOSFET Formulas

Self Induced Resistance is the internal resistance that occurs due to the presence of the FET’s own charge carriers (electrons or holes). And is denoted by R_si. Self Induced Resistance is usually measured using the Kilohm for Electric Resistance. Note that the value of Self Induced Resistance is always positive.

FAQ

What is the Self Induced Resistance?

Self Induced Resistance is the internal resistance that occurs due to the presence of the FET’s own charge carriers (electrons or holes). Self Induced Resistance is usually measured using the Kilohm for Electric Resistance. Note that the value of Self Induced Resistance is always positive.

Can the Self Induced Resistance be negative?

No, the Self Induced Resistance, measured in Electric Resistance cannot be negative.

What unit is used to measure Self Induced Resistance?

Self Induced Resistance is usually measured using the Kilohm[kΩ] for Electric Resistance. Ohm[kΩ], Megohm[kΩ], Microhm[kΩ] are the few other units in which Self Induced Resistance can be measured.
