Unformatted text preview: For Icm I I v v v = = 2 1 , the current thru 2R 1 is 0 and therefore the voltage passes thru those amplifiers with no amplification which is an advantage for the CMMR. EFFECT OF FINIE OPENLOOP GAIN AND BANDWIDTH ON CIRCUIT FERFORMANCE Frequency Dependence of the OpenLoop Gain Expressing Gain in Decibels. A decibels in gain Voltage log 20 = b s A s A ϖ / 1 ) ( + = b j A j A / 1 ) ( + = At high frequencies, j j A j A j A t b b = = ≈ / ) ( Nominal Gain + 10 V/V Nominal Gain 10 V/V ft = 1mHz.
