OPERATIONAL AMPLIFIERS AND DIODES Sample Problems - Dr. Aydın ˙ I. Kars ¸ılayan 1. In the circuit below, assume that all opamps are ideal. (a) Find the transfer function T ( s ) = V o ( s ) /V i ( s ) . (b) Sketch the magnitude Bode plot of T ( jω ) . (c) Find V o ( t ) for V i ( t ) = 0 . 01 sin(2 π 10 4 t ) . (d) If the slew rate for all opamps is0 . 5 V/μs , ﬁnd the maximum amplitude of sinewave input ( V i ) at 20 kHz before the output distorts. (e) Simulate the circuit to verify your results in (a)-(c). Provide the schematic and all necessary plots with measure-ments. +-V i 1k R 1 R 2 2k U 1 4k R 4 R 5 1k R 6 1k R 7 24k R 8 3k U 2 6k R 9 C 1
