I need some general formulas for calculating the overall signal bandwidth of chained op amps. The only formula I have now is: 'f_A = f_t/(1 + R_2/R_1) Where f_t= a_0(f_a) a_0 = dc gain f_a = frequency repsonse of the open-loop response And R_2 and R_1 are the resistors of the standard nonverting op amp configuration. Does anyone have anything simpler than this? Thanks.
