... However, note that this error is multiplied by one-half of the excess gate voltage VGS –Vt. The excess gate voltage is typically much larger than the BJT thermal voltage VT (a few volts versus 25 mV) ! As a result, the Input Offset Voltage for a MOSFET differential pair can be fairly large (e.g., >> ...

Electrical ballast
An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
