Early Voltage in BJT Formulas

The Early voltage is a phenomenon that occurs in BJTs due to variations in width of base region as the collector-base voltage is changed. This effect changes its current gain and I/O impedance. And is denoted by V_A. Early Voltage is usually measured using the Volt for Electric Potential. Note that the value of Early Voltage is always negative.
