Early Voltage in Transistor Amplifiers Formulas

Early voltage is entirely process-technology dependent, with the dimensions of volts per micron.Typically, V; falls in the range of 5 V/μm to 50 V/μm. And is denoted by V_a'. Early Voltage is usually measured using the Volt per Meter for Electric Field Strength. Note that the value of Early Voltage is always positive.

FAQ

What is the Early Voltage?

Early voltage is entirely process-technology dependent, with the dimensions of volts per micron.Typically, V; falls in the range of 5 V/μm to 50 V/μm. Early Voltage is usually measured using the Volt per Meter for Electric Field Strength. Note that the value of Early Voltage is always positive.

Can the Early Voltage be negative?

No, the Early Voltage, measured in Electric Field Strength cannot be negative.

What unit is used to measure Early Voltage?

Early Voltage is usually measured using the Volt per Meter[V/m] for Electric Field Strength. Kilovolt per Meter[V/m], Millivolt per Meter[V/m], Microvolt per Meter[V/m] are the few other units in which Early Voltage can be measured.
