common mode gain 예문

• Minimization of common mode gain is usually important in non-inverting amplifiers ( described below ) that operate at high amplification.
• In the circuit shown, common-mode gain is caused by mismatch in the resistor ratios R _ { \ text { 2 } } / R _ { \ text { 3 } } and by the mis-match in common mode gains of the two input op-amps.
