Common-Mode DC Voltage in MOSFET Amplifiers Formulas

Common-mode DC voltage is one-half the vector sum of the voltages from each conductor of a balanced circuit to local ground or common. And is denoted by V_cm. Common-Mode DC Voltage is usually measured using the Volt for Electric Potential. Note that the value of Common-Mode DC Voltage is always positive.
